It’s been a couple of years since we took our certification course, but we’re on our way to a diving weekend right now and I just realized that I forgot how to track distance. I remember how to use the compass. If something is, say, 500 feet out at 40 degrees, how do you know when the 500 feet is up?

It’s hard to accurately calculate distance, the two most common ways are by counting your kick cycles and by time. Neither will give you an exact distance however as water movement ect will have an effect. For both of these you will need to measure yourself over a known distance in order to calculate.
