I agree with F18 VB, the GPS technology costs about the same as a digital compass anyway. I know the spirit of the rules is to keep costs down, but in this case i do believe the technology over the last 10 year years has reduced in cost to a point where it is now not an issue.
The other rule I have issue with is the ban on synthetic trapeze lines. It was fair enough when stainless wire was a fraction of the price of dyneema, but now in many areas the dyneema is actually cheaper. By the time you don't have to pay some one to swage up a set of lines it is now significantly cheaper to use synthetic.
How do we get these rules updated to reflect what is actually going on in the real world?
