About the SUB’s
Think of a self-contained underwater motorcycle with a large two foot clear dome keeping your head perfectly dry throughout your ride around the underwater reefs. The "bubble" or dome - is large enough for your head and even your hands. This ensures that you can still wear your eyeglasses and adjust them as necessary. It also means that you are breathing normally - through your nose and mouth - without the need of using snorkel tubes or regulators like you would when diving.
If you choose to take an underwater camera with you - it is very easy to line up the shot by holding your camera up to the outside of the dome.
Your personal sub unit is propelled by a small battery operated engine that you have full control over. The steering console allows you to direct the unit left and right. It also contains your power switch. The ascents and descents are controlled by the safety divers who slowly take you up and down a control line. There is also a buoy that is tethered to your sub, preventing the SUB from descending deeper than the planned 15-20 foot dive.
Life support is provided by air stored in a SCUBA cylinder that uses a regulator to keep air continuously flowing into the bubble. In addition, you also have an instrument panel that shows you how much air is remaining in your tank and your current depth.
Finally, the heavy battery which is the power source, is stored on the floor board. Your unit also has lead weights in the bottom of it. When you combine all of the weight on the bottom of the unit, with the buoyancy created from the large bubble at the top - the result is an extremely stable platform.
