I'm not sure what you're trying to accomplish - pin-pointing a wreck or just finding your way back to your ascent point. Just remember underwater navigation isn't precise.
Some easy tips:
Pick easy to see headings-want 110 or 130 use 120 then look left/right once you're close.
To measure distance you'll have to get a 100 to 200 foot rope. Count how many kicks it takes to swim the length then divide the length by the number of kicks-this tells you how far you go each kick cycle (do it 3-4 times & use your average) Do the same thing again only time yourself instead of counting your kicks. Kicks are more accurate than time, but it's a hassle for longer distances.
Doing a Square plan = 3-90' turns, Triangle = 2-120' turns, use the same length for each leg. You can do any shape as long as the legs are the same length & the turns all equal 360'(but you have to count turning once you reach home- 90x3=270 + 90=360; 120x2=240 +120=360). An easy way to do 90' turns is to stretch your arm out straight, then face the direction your arm is pointing.(BTW (')= Degrees)
Hope this helps.
