i know this post doesnt really belong on this thread, but i am looking for some help. what is the best way to accurately measure your depth from the cave mouth? thanks in advance of any help you may could give me!
Phil Winkler wrote:Or, survey as Jeff says and use trigonometry to determine the vertical extent of each measured angle shot. The sum of the vertical extents of each angle = the total depth of the cave. Keep in mind that some shots may go back up, too.

Like with vertical systems?
