Rolex claim that the Sea-Dweller has come to life as the result of pushing the boundaries of what is possible to the limit. Okay… so it’s a cliché but is it true?

Features of the Rolex Sea-Dweller DEEP SEA

• Time and date functions.
• Waterproof to an incredible 3,900 meters (12,800 feet) through Rolex’s patented Ringlock System (a nitrogen alloyed stainless steel pressure retaining ring that protects the the crystal and case back).
• Like the Oyster Perpetual Submariner, the Rolex Sea-Dweller DEEPSEA also uses corrosion resistant 904L steel in its construction.
• Domed sapphire crystal.
• Titanium alloy case back.
• Stainless steel helium valve.
• Triplock winding crown.
• Unidirectional counterclockwise rotatable bezel.
• Highly visible luminescent blue markers on the dial, hands and bezel.
• Robust and reliable chronometric prescision movement that is extremely resistant to magnetic fields and shocks.
• The Rolex Sea-Dweller DEEPSEA is certified as a chronometer by COSC (Switzerland’s Official Chronometer Testing Institute).
• 904L steel strap that can be adjusted to fit over neoprene diving suits up to 7mm thick.

The Sea-Dweller DEEPSEA is another superb Rolex watch that can be enjoyed by divers who are willing and able to invest in such a timepiece. In terms of functions, the Sea-Dweller is not packed with a multitude of tools and widgets: a dive computer this certainly is not. However, as a diver’s timepiece the Rolex Sea-Dweller is the bees knees.

The Most Robust Rolex to Date?

The Rolex Sea-Dweller has to be a contender for the most hardcore diving watch on the planet. Water proof to an incredible 3,900 (12,800 feet) and super resistant to shocks and magnetic fields, recreational divers will find the Rolex Sea-Dweller practically indestructible. As such it may be a “sledge hammer to crack a peanut” scenario for shallow water divers… more likely the Rolex Sea-Dweller watch will appeal to commercial and deep divers. Of course, if you can happily justify the list price of the Sea-Dweller watch then it can of course be enjoyed by any diver out of the water too.

The helium valve will protect the Sea-Dweller from damage for professional divers who have to use underwater pressurised caissons at depth where helium gas mixtures are used: on ascent the valve will ensure that the watch remains undamaged after a stint in such an environment.

Rolex Sea-Dweller DEEPSEA Review Summary

Rolex Sea-Dweller DEEPSEA watches are, like all Rolex watches, elegant and extremely accurate. It is beautifully finished device that is certified by COSC as a chronometer and is quite literally a stunning watch… assuming you have money to burn.

The Rolex Submariner is not a watch that most mortal recreational divers would ever consider as it is an expensive timepiece. So why is the Submariner so pricey and what are the features that make it worth the expense?

This review of the Rolex Submariner aims to answer these and other questions about this highly prestigious range of watches.

Notes About the Rolex Submariner Watch Range

In the main, the Rolex Submariner comes in a 3 different models:

• Rolex Submariner 40mm in yellow gold
• Rolex Submariner 40mm in rolesor
• Rolex Submariner 40mm in steel

The yellow gold Submariner 40mm is constructed in 18ct yellow gold, has a blue dial and a blue rotating bezel as well as a fliplock bracelet. The rolesor version is composed of steel and 18ct yellow gold but has the same color features as the yellow gold model. The 40mm Rolex Submariner in steel has a steel bezel and strap and a black face.

N.B. Throughout the years Rolex have also released a number of special edition Rolex Submariners, with different colorations and metal build combinations, many of which are highly valued by collectors. However, this Rolex Submariner review only focuses upon the models available from the current Rolex collection.

Main Features of the Rolex Submariner

• Waterproof to 100 meters (330 feet).
• Unidirectional bezel.
• Highly luminous markings on the hands, dial and bezel.
• Hyper effective triplock winding crown that seals water out.
• Perpetual rotor makes Rolex Submariner watches self winding.
• Highly accurate Rolex Oyster movement built to last a lifetime.
• Mechanism constructed of 904L steel (a corrosion resistant, stainless-steel alloy).
• Calendar function.
• COSC Certified by the Swiss Official Chronometer Testing Institute.
• Highly elegant and recognizable design.

The Rolex Submariner is recognized in its own right as being one of the finest timepieces known to man. It is owned by many people who have never dived simply for its reliability and elegance. However, divers can take advantage the benefits that this beautiful watch has to offer above and beyond the aesthetic.

The Rolex Submariner 40mm range is designed to withstand massive pressures. It is guaranteed waterproof to depths of 100 meters/330 feet (although in fairness it will be waterproof beyond this point). Its triplock winding crown, which incorporates 3 gaskets, literally screws down like the hatch on a submarine making the Submariner impervious to pressures of 500 bars (equal to 0.5 tons per cm2).

The Submariner also includes Rolex’s ground breaking perpetual rotor mechanism: a mechanism that was invented by Rolex in the early 1930s. The perpetual rotor enables the Submariner to run continuously as the wearer’s wrist movements wind the mechanism.

Much of the Rolex Submariner’s parts are built using a stainless steel alloy known as 904L steel. 904L steel is corrosion resistant and highly durable making it tough enough to take on any diving environment.

In terms of time functions, Rolex watches are famous for their accuracy. The Submariner maintains this leagcy of near perfect timekeeping due to the high quality manufacture and materials of its moving parts.

Its unidirectional bezel provides you with a tool for measuring elapsed time while diving, whilst vibrant luminous markings on the hands, dial and bezel ensure that your timekeeping is not hampered by darker environments.

Rolex Submariner Watch Review Summary

Reliable, robust and accurate, the Rolex Submariner watch is a truly extraordinary timepiece for the diver who can afford it.

Features of the Dacor Nautica BC

• Expanding belt system that contracts as you descend: BC inflation or descent does not interfere with the overall fit of the Dacor Nautica.
• High-positioned, pull activated dump valve.
• Weight system integrated into the back, which is suitable for ankle and block weights.
• 2 x front weight pockets with a 16lb combined capacity.
• Firm “FlexPak” cylinder locking strap holds your air in place.
• The Nautica’s air cell is of the single bladder variety: it expands away from the body so does not squeeze when it is inflated.
• An overpressure/dump valve positioned low on the Nautica makes for easy air release in any position.
• Ample padding at each body contact spot.
• 4 x useful D-rings.

Why Dacor’s Nautica is a Safe Bet

So we have established that Dacor’s Nautica is not the fanciest BC on the block but it delivers everything that most recreational divers would require. In fact many experienced divers continue to use the Dacor Nautica as a testament to this.

The Nautica is a comfortable and reliable buoyancy compensator ideally suited to all environments apart from extreme situations where a more rigourous BC would be required. As a result the Dacor Nautica is a more competitvely priced option for those who never intend to dive in wrecks, caves or under ice. Having said this it is made with a fairly durable nylon material and so it can take some rough treatment.

The Dacor Nautica also has some nice touches such as the weight pockets, which are well placed to enable an almost perfect swimming position, a well sized and positioned ditchable weight system at front as well as the air cell that inflates outwards. The Dacor Nautica is also well padded and comfortable and can be adjusted to fit many different shapes and sizes.

Dacor Nautica Review Summary

The Dacor Nautica BC is a nice little performer that is very well priced. It gives good lift and can be deflated easily and quickly. Although it might not tick every box for the hardcore extreme diver, the Dacor Nautica should be perfect for most others.

Why do Aqualung claim that the Legend ACD Supreme is so good? Are their claims about it justified? And what exactly are the stand out features?

Features of the Aqualung Legend ACD Supreme

The Aqualung Legend regulator includes the following specifications:

• ACD stands for “Auto Closure Device”. The Legend’s ACD keeps the inlet fitting of the regulator sealed (DIN and Yoke) whenever the regulator device itself is removed from your air tank. This means several things:
  • Water and other contaminants cannot enter the first stage. As a result, the first stage itself will retain its level of performance over time and makes it safer to use with Nitrox.
  • The sealed dry chamber also provides resistance to freezing, keeping the mechanics of the Aqualung Legend regulator both clean as well as dry.
• The second stage is pneumatically balanced to ensure consistently easy inhalation regardless of tank pressure.
• The Aqualung Legend ACD Supreme also comprises Venturi Adjustment Switch technology (VAS – controlable by the diver). The VAS prevents free-flowing air when you are at the surface but allows maximum flow beneath it.
• The Legend ACD Supreme also includes Aqua Lung’s Air Turbo System technology in its forward pressure ports which further enhances the breathing capabilities of the regulator.
• The Legend’s over-balanced diaphragm first stage design also improves breathing performance at depth.
• The Legend ACD Supreme regulator is coated with a polyurethane layer which protects its water facing metal parts from corrosion.
• It has 4 x low pressure and 2 x high pressure ports, which are positioned for the best possible configuration of your hoses.
• Recommended for cold water use below 10º C (50º F): the Legend ACD Supreme passes CE standards for cold water regulator performance.
• A removable lip shield on the second stage provides cold protection to your lips.
• 2 year manufacturer warranty.

Aqualung Legend ACD Supreme Review Summary

The Aqualung Legend ACD Supreme is a cold water verison of the Aqualung Legend ACD and is a very reliable regulator largely due to its ACD technology.

The sealed first stage completely protects it from contaminants (when removed from the cylinder valve) in any environment. So cleaning and transporting this particular Legend model should not result in contaminant damage and any subsequent performance degradation over time. The ACD also means that the Legend ACD Supreme is highly suitable for Nitrox diving.

Further features are an overbalanced first stage diaphragm combined with a pneumatically balanced second stage. These features enhance air supply as you descend at the same time as reducing breathing resistance making it easy to inhale. As the second stage is pneumatically balanced it does not require any form of adjustment from you.

The second stage is small and lightweight and can be combined with a number of supplied mouthpiece fittings: an ultra-comfortable model, a standard spare and a reusable clamp.

A lip shield can be used to help keep your lips warm in colder waters, for which the Aqualung Legend ACD Supreme is extremely well suited.

The Aqualung Legend ACD Supreme is a reliable and easy to use regulator that performs well in both warm and cold water.

The Aqualung Pearl i3: Style and Performance Entwined

The premise of the Aqualung Pearl i3 is clever: targetting female divers with customized dive gear. As such the i3 works on many levels: it looks very feminine, comes in several different colors and offers up all the features you would expect of a quality buoyancy control device.

The Aqualung Pearl i3 Review Summary

Comfort AND functionality have been well thought out. The Pearl i3 has successfully incorporated a padded back lining, neoprene rolling collar and built-in supporting sports bra. The adjustable (by 6 inches) waist-band gives divers the opportunity to find a perfect fit.

The design of the Pearl i3 BCD’s bladder means that it expands away from the back rather than to the sides, resulting in a more appealing shape when inflated. The overall contouring of the i3 also tends to enhance body shape.

The Aqualung Pearl i3’s easy-dump valves, easy-deploy oral inflator, cylinder traction pad, utility pockets and durable materials used in its manufacture shout quality.

The i3 is easy to put on and take off even when fully loaded, and once you are strapped into it adding or removing weights into the weight pockets requires little effort or discomfort.

The Pearl i3 also has useful, usable and well-sized utility pockets and a number of d-rings for clipping your required tools on to.

Combined with its feminine design, the features of the Pearl i3 are certain to make the Aqualung feminine BCD appeal to its target audience.

Chic looking, comfortable and above all truly functional, Aqualung’s Pearl i3 is a real winner.

Background on the Omega Seamaster Watch

Like the Rolex Submariner, the Omega Seamaster watch has become a classic diver’s watch. The Seamaster began its life in 1948 with the manufacture of the Omega Seamaster Standard and Chronometer ranges. However, in those days the Seamaster was really little more than a waterproof dress watch… it was certainly not a hardcore diver’s watch. It was not until the 1970s that the Omega Seamaster became more dive-centric.

During the 1970s the Seamaster was built to withstand serious depth as well as provide chronograph functions, rotating bezels and high-vis luminous dials to make them it easy to read underwater. In 1993 the Omega Seamaster Professional (a.k.a. the Omega Seamaster Pro) was launched. The Seamaster Pro is a model of style and substance for divers: it can be taken down to 300 meters (way more than necessary for recreational diving) and offers a host of useful functions for any diver.

The Omega Seamaster Professional Diver’s Watch

The Seamaster Pro is commonly known as the Seamaster 300m, due to its depth capability. It is available in quartz and automatic movements with versions for men and women. The men’s Omega Seamaster Professional comes in two models:

• One has the classic 1993 “skeleton hand”;
• the other has thicker hands known as the “GMT style”, which was released in 1998.

The Seamaster Pro Diver and James Bond

The Omega Seamaster Professional Diver is one of the most popular watches in Omega’s collection. This is thanks, in no small part, to the James Bond movie franchise. The Bond character wore Omega’s Seamaster for the first time in 1995 in the movie Goldeneye. This brought not only the watch to public attention but launched Omega’s public profile enormously. The Omega Seamaster Professional watch is still appearing in Bond films.

Primary Features of The Omega Seamaster Pro

• Water resistant to 300 meters (1,000 feet).
• Screw-in caseback, screw-down helium release valve and screw-locked crown.
• Rotating bezel.
• Luminous hands.
• Self winding movement (includes 44-hour power reserve for when the Seamaster is not being worn).
• Chronometer.
• Highly accurate timekeeping.
• Date window.
• Scratch resistant sapphire crystal.
• Stainless steel case with rhodium-plated strap.

Omega Seamaster Review

The Omega Seamaster watch is a near flawless example of watchmaking on any level. It is a highly attractive timepiece that sits easily on the wrist of anyone be they a diver or not. It is as a diver’s watch though that the Omega Seamaster Professional really comes into its own.

The Seamaster is extremely durable and tough (to 300 meters) and is highly visible to read underwater. You never have to worry about its batteries failing due to its self-winding movement and above all it is a highly reliable piece of equipment.

Its black face and luminous hands and markers make it very easy to read in dark and murky conditions, while its black aluminum rotating bezel with silver coloured ten-minute markers enables you to clearly monitor dive times.

Quite simply, the Omega Seamaster watch range is awesome… but the Seamaster Pro is sublime. It is a fairly expensive watch to own, but by purchasing an Omega Seamaster watch you are investing in something that will potentially last you a lifetime.

The TUSA Liberator Sigma BCD (BCJ-3200) is a comfortable BCD designed for SCUBA divers of all levels of ability.

It’s also an economy BCD that incorporates a number of TUSA patented features.

But is the Tusa Liberator BC more comfortable than other BCDs in its class and price range? And does it offer more than your average BC?

What Does the TUSA Liberator Sigma BCD Offer?

TUSA’s Liberator Sigma BCD is constructed with heavy-duty 840 denier nylon shell to give it durability and strength. Its “Advanced Weight Loading System” has been designed to make loading and releasing dive weights a simple activity: the Liberator BCD’s AWLS design allows for the easy switching of weights into/out of “cartridges” located in the front of the jacket and shoulders. Thus the TUSA Liberator BC eliminates the need for an ungainly weight belt.

TUSA Liberator BCD and Stability

The Liberator Sigma BCD has a neat harness system that is independent from the BCD itself and includes two well placed rails in back. Your tank straps to the rails via a stabilizing harness. The harness in turn is connected to the Liberator Sigma’s shoulder straps, which help to support the full weight of your tank.

However, the stabilizing harness remains independent from the actual Liberator BC jacket, ensuring that your tank remains very close to your body regardless of the change in size of the BCD when you inflate or deflate it. This makes the TUSA Liberator Sigma BCD very stable and less likely to cause your tank to roll both underwater and prior to your descent before you even get wet!

Principal Features of the TUSA Liberator BC

• Attractive design constructed with 840 denier heavy-duty nylon for extra strength and ruggedness.
• Clever independent stabilizing harness that ensures tank stability and enhanced bouyancy control.
• TUSA Liberator Sigma BCD AWLS (Advanced Weight Loading System) that removes the need for weight belts.
• Two large and useful front zip-pockets.
• D-ring (made of stainless steel) at right shoulder for attaching accessories.
• Fast inflation and deflation (the TUSA Liberator BCD also includes a quick dump valve at the rear of the jacket).
• Easily-adjusted chest strap.

TUSA Liberator Sigma BCD Review Summary

The Liberator Sigma BCD builds upon TUSA’s solid range of BC jackets. It provides a comfortable fit due in a large part to its stabilizing harness system and the way in which it assists in holding your tank firm while you inflate and deflate your it during your dive.

Its hardwearing nylon ensures it can stand up to most recreational diving environments without complaining.

The Liberator’s weight management system is straightforward, and details such as the obligatory D-ring for clipping your odds and ends onto provide a nice touch. The Liberator Sigma BC also has two very usable and useful zippered front pockets.

Try-Diving’s verdict is that the TUSA Liberator Sigma BCD is a good budget BC jacket for divers of all competencies.

The Princeton Tec Impact II is a flashlight designed for SCUBA diving as well as for outdoors use. It is a small but powerful light that is strong enough to withstand the pressures that diving and divers make of it.

The Impact 2 is a smaller version of the Princeton Impact XL flashlight and so has many of the same qualities. It has a strenghtned glass lens, a clip and ring that will fasten tidily to a BCD or harness and has a nice oval design that fits perfectly into a diver’s hand (not too small and not too big). The Princeton Tec Impact II also claims to use its power supply in a fairly efficient manner providing a pleasing 75 hours of usage per each new set of 4 AAA Alkaline batteries.

Princeton’s Tec Impact II has been tested in cold and warm water environments to depths of 100 meters (300 feet) and so it is more than capable of satisfying the needs of all recreational divers. Its proprietary optics system magnifies its Ultrbright LED turning it into a sharp and precise spotlight that delivers a targetted beam up to 28 meters ahead when the visibility is good. For such a seemingly small device the Princeton Tec Impact II delivers in spades!

Princeton Tec Impact II Technical Specifications

• Waterproof to 100 meters (300 feet).
• Utilizes high quality and extremely efficient blue-wite Nichia Ultrabright LED.
• Strenghtened Princeton Tec proprietary optical lens that powers the Ultralight LED to distances of up to 28 meters.
• Rugged Princeton Tec build.
• Ergonomically designed handle.
• The Impact II has a clip and ring for easy fastening to other equipment.
• Powered via 4 AAA alkaline batteries that give up to 75 hours usable light.
• Lightweight: 2.85 oz (81g) including batteries.
• Easy to transport/carry: Dimensions – 5″ (12.7 cm) length x 1″ (2.5 cm) diameter.

Princeton Tec Impact II Review Summary

The Princeton Tec Impact II is highly impressive diver’s flashlight. It is small and lightweight and can be easily attached to your kit, both underwater during your diving activities and overland when you are out and about.

Its efficient Nichia Ultrabrite LED gives just about as much illumination as you will need during night dives or wreck and cave diving (assuming reasonable visibility). Its plastic casing and strengthened lens make it a tough little performer that can be depended on time and again.

Princeton’s Tec Impact II is highly recommended for recreational diving and is well priced to make it accessible to all.

Why Does the DUI TLS-350 Drysuit Have Such Fans?

Most divers who have used the DUI TLS-350 claim that the fit feels like you are diving without a drysuit. This is largely due to the fact that the DUI TLS-350 drysuit is constructed using lightweight and very malleable trilaminate that is well suited to the the underwater world. TLS-350 DUI drysuits are also able to cope with harsh diving environments.

So what DUI TLS-350 drysuit owners get is a comfortable divesuit that:

• tends to be less restrictive than others;
• can perform well under demanding conditions;
• can be transported easily due to its light weight;
• dries quickly due to its trilaminate build.

Features of the DUI TLS-350 Drysuit

• Extremely lightweight trilaminate fabric (Nylon/Butyl and Rubber/Nylon).
• Diagonal zipper that allows front entry.
• Low profile exhaust dump and low pressure inflator swivel inlet.
• Warm neck collar for using along with warm neck hood.
• TLS-350 telescopic torso, which makes donning and doffing easier.
• Close fitting yet less restrictive than other drysuits.
• Includes a zipper guard that protects the dry zip.
• Incorporates an adustment cord inside the drysuit for a perfect waist fit as well as a strap and braces to hold the TLS-350 drysuit firmly in place.
• Rockboot system.
• Double layer trilaminate fabric protection covering the knees.
• Full DUI manufacturer’s warranty.

Summary DUI TLS-350 Drysuit Review

The DUI TLS350 drysuit is a really comfortable and travel friendly suit. It is robust enough to cope with tougher diving envrironments (such as caves and wrecks), gives enough room for you to wear underclothes in colder locations but remains not excessively warm when used in waters of a more moderate temperature.

DUI TLS350 drysuits are easy to put on and take off through their smart across the shoulder front-entry zipper and telescoping torso design, and they can be used in freshwater or saltwater. They also dry quickly when you are done using them.

What more could you want from a drysuit?
