There are at least two different patented “instant dive” systems being used at tourist resorts around the world. Neither requires any scuba training. Their purpose is to provide a fun underwater exploration experience for individuals and groups who’d like to try diving or “advanced snorkeling”, but aren’t ready to invest the time and the money in a full scuba course on their holiday.
Q1: How do these 12 Volt Diving systems work?
A: The PowerDive range of 12 Volt operated products utilises either a small, but highly efficient, 12 Volt operated ‘oil-less diaphragm’ or ‘oil-less carbon sleeve piston’ air compressor and a combination of diving components to provide a realistic and safe alternative to traditional diving equipment, such as Scuba. There are three different types of 12 Volt units. The ‘DeckSnorkel’, the ‘”Double DeckSnorkel’ and the ‘ExtremeSnorkel’ all remain on your boat, powered by the boat’s battery and are perfect for underwater boat maintenance (they can also be used for fun diving out of a dinghy or inflatable). The PowerSnorkel floats on the surface, powered by its own internal rechargeable battery and is designed mainly for recreational diving.
The SuperSnorkel range of Petrol (Gasoline) Hookah systems for deeper diving use wobl piston technology. These units are deck models designed for depths between 15 and 40 metres.
Q. What equipment do I wear?
A. You will be wearing a pair of fins, a mask, a weight belt (to neutralize your bouyancy in the water) and a SNUBA harness which connects your air line to the raft on the surface.Q. How deep can I dive?
A. The depth is limited by the length of the air lines which allow you to dive to a maximum depth of 20 feet.
Snuba uses compressed air supplied from a tank on a floating raft. Powerdive has a floating compressor that provides low-pressure air via a hose. I’ve tried both of them and much preferred the Snuba approach because it provides air with consistent pressure unlike the Powerdive system.

I found “Open Water” DVD in the bargain bin and watched it the other day. It is psychological mini-disaster movie and is rather well executed for such a low budget production. All the sharks in the film are real and the film gets better and better after the uneventful and predictable plot set-up segment. It is loosely based on a true story which apparently isn’t that uncommon.
