What is the 120 rule in diving?
Subtract the depth you’re diving (in feet) from 120. The resulting number is the maximum amount of minutes you should spend at that depth. It’s mainly for recreational divers using air, not Nitrox or other fancy gas mixes. Here’s how it works: Your max depth (in feet) + your bottom time (in minutes) should be less than or equal to 120. That’s it. So if you plan to dive to 60 feet, the rule says you shouldn’t stay down longer than 60 minutes.

The rest, in most cases, is pretty much secondary. The most frequent known root cause for diving fatalities is running out of, or low on, breathing gas, but the reasons for this are not specified, probably due to lack of data. Other factors cited include buoyancy control, entanglement or entrapment, rough water, equipment misuse or problems and emergency ascent.Never hold your breath. This is undoubtedly by far the most crucial of all safety rules for diving because failure to adhere could result in fatality.

What are the 4 positions in diving?
Diving positions for platform and springboard diving are based on four distinct shapes. These are straight, pike, tuck, and free. During competitions they are referred to as A, B, C, and D. Dives can all be put into one of six categories: forward, backward, reverse, inward, twisting, and armstand. Which category any given dive fits into is determined by the diver’s orientation in relation to the water and the diving board, as well as the direction of their rotation.
