Guys, if you are looking for secure snaps or shackles for securing gear to equipment lines ON THE SURFACE then look at the type of snaps that come on jack lines or safety harness tethers. West Marine and other yachting type stores have a large selection of these type of snaps and lines. Offshore sailors snap into safety lines so they don't get washed overboard and lost. My West Marine catalog shows webbing jack lines with large stainless steel carabiners sewn into one end in lengths from 25' to 75' and they have all sorts of other safety tethers with snap shackles, snap hooks and double-gated Gibb snap hooks. This stuff is lifesaving gear on sailboats and is way more than adequate to secure your precious set of doubles. They even show some safety tethers with elastic sections built into the webbing which might be a good idea for clipping off gear in heavy seas. There's basically a proportionate relationship between the degree of security and the ease of release. Snap shackles are very easy to release but are less secure. Gibb snaps are very secure but will be more difficult to release under load and with one gloved hand. As for climbing carabiners. I happen to be using standard climbing carabiners on my jon lines and to clip off the running line that runs between my anchor line and the deco station at the stern of my boat. They seem to work fine underwater and are nice for jon lines because you can take them off the line if you want to double it up. They are easier to handle with mits than the standard SS carabiners. They do corrode eventually if you don't keep them rinsed and dry. Climbing carabiners are built from lightweight alloys because weight is a critical factor if you are hanging 1000' up on a rock with all sorts of hardware hanging off your harness. Stainless steel carabiners would be too heavy for climbing use. However, in the marine environment weight is not a factor so there is no reason not to use corrosion proof stainless steel equipment. The only reason I use the climbing carabiners is because I have a pile of them in the garage from my climbing days. For stages I use the regular stainless steel bolt snaps -Kent- Paltz, Art wrote: > > I agree Dave, > > I don't doubt that it can be done, Yes I've had to do it myself.
