I believe theres an app for smartphones and tru-trip dive charts, although, I kinda go with the 3/1 approach, gets me pretty close, 115 to my tally would be about 27-29 ft, although speed has alotto do with it also, 2.5-2.8 would run around 20', Mike

I got nervous when I saw that you use a 3 to 1 approach. I always thought it was 2 to 1, after checking the dive charts I see it's both depending on the depth, shallow is more 2 to 1 and deep is 3 to 1 or more. Now I'm off to find the app for my iPad!
