Editor’s note: The following piece on the Dreager LarV was written by retired Delta Force Master Sergeant George E Hand IV. While this piece discusses special operations equipment, it does not reveal any classified information.
Recreational SCUBA diving with standard compressed air can give a diver about an hour of bottom time. That of course is largely dependent on the depth the diver spends his time at; the deeper one goes the less time he has at depth. A rule of thumb is 60 feet for 60 minutes and then you should come out of the water. The longer you stay at depth also governs how long you must wait on dry land before you can go back to SCUBA diving.
Imagine now being able to stay underwater for more than four hours without ever even exhaling a single bubble. The military has a system that “breathes” pure oxygen (O2) and is based on a closed gas system. SCUBA features an open gas system; that is where each exhaled breath is released out into the water and rises to the surface where it stirs up the water and creates an unmistakable profile that there is a person diving down below.
