About Tusa Package #3

The RS-680 Regulator delivers Superior Performance and Quality in a Compact Lightweight Design. The R-600 mated with a newly developed S-80 Second Stage further pushes the engineering and performance envelope. The Compact Chromed Marine Brass Balanced Diaphragm R-600 First Stage is Incredibly-Small and Weighs only 22.2 oz (630g). The R-600 is configured with 2 HP and 4 LP Ports. The Balanced Diaphragm, First Stage Regulator is inherently Environmentally Sealed. The benefit of this type of first stage design is that none of the delicate internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants can cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance.

The S-80 Second Stage offers the following features: S.E.A. - Sequential Exhaust Assist

The Sequential Exhaust Assist (S.E.A.) is a Second Stage design featuring a Dual Exhaust System. The S.E.A. System consists of an Enlarged-Primary and an Auxiliary Exhaust. The Auxiliary Exhaust, located on top of the S-80 Elliptical Case, works in union with the Primary to Significantly Decrease Exhalation Resistance. Exhalation Resistance Directly-Affects the Diver's Natural Breathing Cycle, Reducing this Resistance the diver Breathes-More-Naturally and Comfortably Reducing Respiration Rate and Air Consumption.

Venturi Adjustment
The Venturi Adjustment Lever on the S-80 allows the Regulator to Power-Assist the Diver when underwater utilizing the Natural-Venturi Effect. The diver may also Adjust-the-Lever to Prevent Free Flow such as on a Surface Swim.

Moisture Exchange Plate
The Second Stage has a Moisture Exchange Plate that Captures-Condensation produced by Inhalation and Exhalation Efforts. This Condensation Increases the Humidity of the Air Breathed and helps to reduce that "Dry Mouth" sensation often experienced while diving.

Breathing Resistance Adjustment Control
The Breathing Resistance Adjustment Control on the S-80 allows the diver to Adjust the Flow of Air according to their needs. The Easy-Adjust Multiple-Click Knob allows you to Quickly-and-Finely Tune Breathing Resistance. The Ortho-Consciously Mouthpiece further enhances the Comfort of Bite, Fit, and Stability. Even with a Light-Bite, a High Level of Stability is achieved so there is no Fatigue from long periods of usage. For Optimum Performance and Comfort, a 29" (74 cm) Swivel Hose is fitted between the S-80 Second Stage and the R-600 First Stage. The Swivel-Joint allows Flexibility of the Hose to Eliminate Hose Tension. The S-80 is a Reliable Down-Stream Demand Valve Design.

TUSA Dual-Air Alternate Combo Inflator
When you took dive lessons you learned to perform specific skills to make you safe and comfortable underwater and at the surface. One of those skills was Buoyancy Control. Once you start diving for fun you use your Buoyancy Control Devise constantly throughout the dive. Your Octopus or Alternate Air Source Devise on the other hand is never used unless there is an Emergency Out-of-Air Situation. Reacting properly in an Out of Air Situation can make the difference between a Safe Dive and a Tragedy. If your Alternate Air Source and your BCD Inflator Devise are one and the same you will always know where to find it in an emergency.

In an effort to continually meet the needs of today's divers, TUSA is expanding their regulator line with the Inflator Regulator. It's a downstream backup regulator that also provides you with easy-to-operate buoyancy control. The Inflator Regulator is positioned at the end of the buoyancy compensator hose, the ideal location for quick, efficient use. Because you use it as your power inflator, you always know where it's located. Plus, the Inflator Regulator cuts down on hose clutter because you use the same hose to supply both the power inflator and the backup regulator. The regulator features a dependable down-stream demand valve mechanism. The Regulator's Pre-Tuned System is housed in a Carbon Fiber and Techno-Polymer Case for Strength and Durability. The Demand Valve is Chrome Plated Brass with a Stainless Steel Spring and a Silicone Rubber Diaphragm and Exhaust Valve. The Dual-Air comes with a 3/8" Threaded 27.56" (70 cm) High-Flow Low-Pressure Hose. The Primary and Dual-Air Regulators comes with Owner's Manuals and are covered by a Limited Lifetime Warranty.

The Pro-Plus 2.1 offers Large, Easy-to-Read Alphanumeric Displays and Color Coded Graphs where Green means "Go," Yellow means "Caution" and Red means "Stop." There are user settable Audible and Visual Alarms. Alarms include: High 02, High and Maximum P02, Turn-Around Time Tank Pressure, Maximum Depth, Elapsed Dive Time, Maximum Nitrogen and Dive Time Remaining. The Computer has Graphic Indicators for Air Time Remaining, Oxygen Loading, No Decompression Time Remaining, 02 Time Remaining and Ascent Rate.

The Computer can be Manually Turned-On or Water Activated. The CR2 Battery is User-Replaceable at any time without the loss of data. The Computer Displays Temperature and Time of Day, although suitable for sport divers the Computer it can be used as a Computer for Air/Nitrox or Depth Gauge to 330' (100 meters). It offers both Tim-to-Fly and De-Saturation Countdowns. It Automatically Adjusts for Altitude and for Salt or Fresh Water. The Computers Algorithm is a Modified Haldanean / DSAT (Diving Science and Technology) Database. The Computer has an On-Unit Log Capacity of 24 Dives, Backlighting, Side Scan Compass, Quick Disconnect Hose; Owner's Manual and is covered by a 2 Year Limited warranty.

The Evolution Platina BC is Full Featured Jacket. The Evolution Platina offers TUSA's Advanced Weight Loading System (A.W.L.S.), the Independent Harness System, and the Ultimate Stabilizing Harness. The Evolution Platina has TUSA's Waist Support System allowing for Customizable Shoulder/Harness Fit. Rear Trim Pockets combine with the A.W.L.S. to optimally balance the weight load. The Jacket has a weight capacity from 24 to 28 lbs (10.9 to 12.7 kg) with 16 to 20 lbs (7.26 to 9 kg) Dump-Able. TUSA's Ultimate Stabilizing Harness relieves tank roll and delivers an amazing fit. The U.S.H. securely holds the air tank in place with optimally placed rails and brings the tank closer to the body increasing tank control while reducing weight. The Waist Support System significantly enhances comfort and fit by dispersing the weight load around the hips. The W.S.S. integrates the adjustable shoulder harness system with the rear stabilizing plate and cummerbund to effectively unload the hips while ensuring a snug fit. BCD provides 24 to 44 lbs (10.7 to 19.9 kg) of Lift, comes with a Owner's Manual and is covered by a 12 month limited warranty. Included in the package is a Leisure Pro Ball Cap.

      Questions & Answers Powered by TurnTo®

      Questions about this item:

      Shopper  Is the regulator RS-530 that comes with package # 3 for cold water use ?
      Chris L  If I'm not mistaken, it is rated for temps above 10 degrees Celcius [50F]. The lowest I've been in was 44F but only for about 15 minutes. It is recommended to get a cold weather kit for other temps. I generally dive in warmer climates so n o factor for me. This is an awesome regulator for the price. Very good performance overall with good response.
      Greg H  How does the sizing work for men and women?
      GARY K  Hi Greg, Because I purchased this BC for my daughter, I'm only going to be able to tell pass on some info for a woman's BC. The vest has worked out extremely well for my daughter and she has found it not only very functional but also very comfortable and unrestricted by the straps etc. Here are some comments from my daughter: "Hello! I'm not entirely sure what size would be best for you, but I am 135lbs and 5'5'' and I have a Small (Euro)/ Medium (Asia) BC and it fits like a glove. I've worn it both with and without a wetsuit, but usually with. It's also adjustable, as are all of the jackets so you could probably fit any of them to you. The large might be too big for you, but again, I'm not sure. The best thing to do is to go to your local dive shop and try some other BCs on for size, then once you know your size, buy one online for cheaper (unless you want to support your local dive shop!) -- Best of luck and happy diving -- Kristin" Hope this helps you out.. Gary
      Shopper  Does this package have compass?
      LeisurePro S  Sorry, no, the Cobra does not have an electronic compass-- a traditional compass can be purchased seperately.
