Best knot for bungee/shock cord

[thehotcorner]

I've attached my DSMB to the bottom of my backplate using some shock cord. I made the loop using a regular overhand knot and was wondering if there might be a specific knot better suited to the task.

I use a poacher's knot for most of my dive gear. Works very well in water.

I don't understand this. Can you provide a pic? I attach my smb and spool with a bolt snap to my tail ring on crotch strap--reachable but out of the way. For any knots I tie using shock cord that are meant not to come off, I use a square not. But maybe I'm not understanding how exactly you're employing the knot.

Guess I just got my knots wrong. Actually using a square knot (2 ovehand knots?) to tie off a loop of cord through one of the holes in the harness.

You can only pull from one side that way right? Or at least you risk getting the spool tangled in the bungees the other way? If you rig like that, I'd use a square knot.

I have found that, in tying bungee, it's important to really stretch the line while tying the knot. The rebound of the elastic really helps the knot stay tied.

I usually just tie a basic knot around the end of the bungee line (feeding it back through itself, kinda like a "figure 8") and use 1 or 2 zip ties to keep them together. Works very well for me and I can take the bungee off easy because all I have to do is clip the zip tie versus trying to untie the full knot.

For making a loop, I usually use a double fisherman's knot.

I have also had good luck with the blood knot...just remember to stretch the bungee tight.

I have not found any knots that have been reliable enough on bungees. I just dab the knot with Aqua Seal or comparable adhesive... end of problem. Silicon adhesive is a little weak for this application.
