Triplelooping Compass

[alewar]

I've got my first compass and now I have to properly lace the bungee cord around it. I found some variations of this here in SB, including using one or two cords, and crossing the cords on the back or not. None of them is entirely satisfying. What about lacing it like this?:

I prefer to use two separate pieces of bungee, one for each side. The reason being that if a single cord is used, and a knot gives out or there is a break, the other side will loosen up.

That's how I did mine,too.
I'm trying to figure out how to do my Liquivision Xeo. Wondering if the DSS bungee setup is much better than DIY?

That's a nice question for a college probability course: How much smaller is the probability that two opposing knots fail having four knots in total, compared to the probability of 1 knot to fail having two of them. I could write an article in the Quest Magazine

Joke aside, do you leave the knots facing upwards or downwards?

Are you talking about for a compass or your Xeo? For a compass the DSS mounts work great. But you don't need a mount for the Xeo, it already has holes to run the bungee through on the body. One loop on each side and go diving.

I keep the knots turned down since I think it looks neater, and also if the bungee mount gave out, the knot would have to pass through two holes to become loose.

However, I think the reasons for me doing it this way are at best only slightly better and at worst only slightly worse than the alternatives, so not really worth putting a lot of thought into.

A bigger issue I have with the routing shown in the picture is that using that I would have to pass my drysuit cuff through 3 bungee loops instead of two

I use one piece, but tie knots in it each time it goes through the holes so that if it breaks, it only effects one part.

Use thinner cord or all the force/stretching to get it over your dry suit rings will cause the plastic mount to crack. I use 1/8" so 2mm or so.

I use 1 piece but it doesn't matter much, the key is to keep the plastic mount holes from ripping out. The cord itself never breaks. If you leave bungie cord in a hot car or something like that the latex fibers will dry out and it won't contract anymore. But the cord still never breaks.
