MikeFerrara:
I guess I just don't see the advantage. If I was concerned about weight and rapid deployment, why would this be any better or faster than any other small light weight bc or wing already assembled to any size tank I want to strap onto it?
ok, now I've gotten into the water fast. Now what's the advantage? I know I don't like a belly mounted tank but I see you can back mount one too. What am I missing? What does the thing do for you? Or what could I do better with it than with any of my other rigs?
As the inventor/developer of the Rapid Diver system, I feel confident to answer the questions about the advantages
You are right in thinking that it is not immediately obvious where the differences lie between the conventional back mount and Rapid Diver system. It is in the application of the technology where the differences become clear. Let me explain.
The first advantage is how we configured the entire unit to take advantage the new, smaller/lighter tank technologies. The complete, ready to dive unit fits into an incredibly small space--about the size of briefcase--and weighs in at just 20 lbs. The Rapid Diver is universal fit and goes on quickonce the unit is adjusted for the user there is only one QD to connect.
2. A custom proprietary tank was created just for the Rapid Diver. We found this tank to have the perfect weight/size/duration for the system. The average diver breathes about .7 cubes per minute which means it would take an average of 28 minutes to breathe down a 20 cu ft tank (at 3000 psi) at the surface. Good divers have an average breathing rate of .5do the math. The tank placement is of key importance and is located in the optimum position for the diver. The geometry is successful because the tank is in the CG and is slightly negative +-5lbs and displays keel like characteristics. Underwater the unit seems to disappear, you feel as if you are free diving. The belly tank configuration is also extremely useful as a shelf for knife/lights and for surface transitsno weight placed outside of the water.
3. The load bearing harness which supports the weight of the tank also allows for a tank to be attached on the back. This was designed to maximize the systems expandability. This means that you can attach a tank on the front, or a tank on the back, or a tank on the front and back. A standard back plate (with or without a buoyancy cell) is a perfect accessory to the Rapid Diver system when doing extended duration diving that require using larger tanks (up to 130s). In this configuration the back mount becomes primary and the chest mount becomes the back up. The configuration possibilities with the Rapid Diver system are almost limitless.
4. Unlike traditional back mount systems, the Rapid Diver can be used as tactical swimmers vest (TSV) without the life support system attached. This becomes a useable piece of equipment for small boat operations, spear fishing, or skin diving activities.
5. This next advantage is fairly obvious, and that is that the buoyancy cell is favorable for heads up safety at the surface. The buoyancy cell provides a solid 25 lbs of lift in fresh water.
6. The Rapid Diver system is a complete package which includes the buoyancy vest, the regulator the pressure gauge, power/oral inflator and a new proprietary aluminum tank, the 20 cu ft aluminum tank. A new high pressure 30 cu ft steel tank is also now available; this tank is slightly heavier and adds around 5lbs to the system.
7. The price. We determined early on that the price point would be a very important factor. The Rapid Diver initial retail price is in the $799 range.
