        Reply to:   RE>Ascenders

I hesitate to recommend them, but I use some old Gibbs ascenders in a lot of
diving applications.  I tried Jumars, they have the advantage of spring loading,
but the open gate caused problems when the load twisted, or took a
less-than-vertical strain.  They also suffered mightily from corrosion.  

The Gibbs units completely capture the rope, but require modification (beef up
the spring) to securely hold on a wet line.  They are small, handy and secure,
but I still use a prusik knot (with a MAJOR difference in line size) in critical
applications.

Hope this helps

Gerry

I want to get a set of ascenders ( like Jumars ) for use underwater 
( and probably above ).  However I have no idea which brand is going 
to be best for use underwater or how to rig them to my gear.  Does anyone 
on this list have any recommendations?
