The rate at which you use air while diving depends on factors such as the depth of your dive, the temperature of the water and your exertion level. Diving 15 to 30 feet in warm, quiet water, you can spend about an hour underwater with an average tank.
Divers use pressure gauges to measure the amount of air remaining in a tank. A handy instrument like the UWATEC; 2 Gauge Console combines a pressure gauge with a depth gauge. Add the optional C-1 Compass, and you can quickly determine how deep you are and in which direction you're swimming-information that lets you range farther from the boat with confidence and safety.
Computers can help your diving
A dive computer delivers key measurements for safer, more accurate diving. Today's sophisticated computers track how long you've been under water and the depth of your dive; calculate the amount of nitrogen in your body; and guide you in making decompression stops as you ascend. Even more advanced dive computers take into account factors such as water temperature, diver exertion to determine remaining bottom time before you need to begin a safe ascent to the surface factoring in any decompression stops needed with a safe backup supply of air.
Such precise nitrogen management makes it possible for divers to go deeper and stay underwater longer without compromising safety. Instead of calculating your dive profile with tables based only on the elapsed time and the deepest point of your dive, you have a profile that considers all the real-life variables. Using a dive computer, you may be able to double the length of your dive.
The Aladin TEC 2G wrist computer, made by UWATEC®, is accessible, easy to use and packed with features. It combines dive functions with an altimeter, average depth indicator and gauge mode with stopwatch functions. SmartTRAK software lets you download and manage dive profiles using your home computer.
