OK, this may mark me as a newbie goofball...
I have been thinking about the issue of keeper potholes as my partner and I have been progressing through the less technical canyons. When we are ready, I think the ultimate keeper pothole technique will be going more experienced canyoneers.
In reading about the various devices proposed, has anyone tried some of the lighter weight tactical breeching gear? I am thinking of a collapsible titanium climbing stick. The first device is called a Ruhl Tech Breaching Folding Pole Ladder with Alternating steps. It is 7.5 feet tall and weighs 9.5 lbs. Don't really know how tall this needs to be but I am sure someone out there does. (ruhltechbreaching.com). Might save a lot of time.
Another device is a folding, menacing hook called a Yates Afgan hook and deploys on a long aluminum pole and carries a step ladder below it. This stuff can be seen in the tactical section of the yates gear website.
I am just saying that if one is willing to spend a grand on a dry suit, why not on a titanium collapsible ladder. If it was on Tom's website and the weight was reasonable even if the price is steep, I'd be a customer if I knew it would increase my safety.
I'd post pictures but I am too young on this site.
