View Full Version : Which bungee for computer/compass?

10-09-2014, 10:02 PM
I'm currently using 5mm bungee on my computers/compass and am having issues. If it's tight enough so that the computers don't slip or move around then it seems too tight for comfort. If it's ok for comfort then the computers seem to slip around my arm.

What am I doing wrong?

Are people typically using thinner 3mm bungee (I used to but it seemed to lose it's stretch and die reasonably easily) that might have more stretch in it? Of is it just a very fine line in sizing the bungee correctly so that it's only just under tension? Or is it as simple as the fact that some bungee is stretchier than others?

I thought about trying surgical tubing instead of bungee as that may have more stretch in it.

I use the 3mm stuff I think and have it reasonably tight. Never noticed a problem.

I've seen people lace the mount in a diagonal pattern, top-left to bottom-right etc. maybe try that.

3mm, it lasts years... two separate loops, if one fails your puter don't fall off none

Ok, consensus so far seems to be that 5mm is too thick. I have ordered some 3mm and some 4mm stuff and can have a play. Thanks.

I found that the cheap 3mm is crap, and doesn't have enough tension in it. if youre buying some half decent stuff then 3mm is fine, if not go 4mm. the bungee on my quantum is 5mm (because that's what was on it when I got it) which is just too thick, and a PITA to get over my si-tech rings. I keep on meaning to replace it, but only remember its an issue when I go to put the 'puter on my wrist.

I have 3mm on my dss mount, two separate loops as BTS says incase of a snap. I would think 5 would be way over the top.

On a related note, the strap on my 5 year old Suunto D4 failed (again) over the weekend.

Is there an easy way of bungee mounting D4s, or do I need to shell out for a new strap?

What bit failed? If the strap (even just a bit of it) is still connected to the computer you can drill a hole in the strap and use that to connect the bungee.

If huge strap is completely bust but the pins still hold in place, can you manage to squeeze a bit on bungee between the computer and the pin? Could run the bungee through there with a retaining knot on it.

A bit like on this page

5mm surgical tubing. Very stretchy, but holds computer/compass/bottom timer nice and tight. Great for making snoopy loops too.

I have found that surgical tubing works the best for me. It will stretch further and therefore will work if I am diving wet, dry, or naked. It also tends to keep things from sliding much better than bungee does, with less tension so it is more comfortable.

Just like bungee, there are various diameters and wall thicknesses. I use 1/4" with 1/16" wall. No I do not use metric. :-)

This method of lacing works well - 2 separate loops therefore redundancy + you can adjust for different thickness gloves ,/ suit http://www.scubaboard.com/gallery/showgallery.php/cat/4487

3mm. laced back and forth multiple times. Dont tie it off, use a whipping.

surgical tube works well, but it seems to age/crack split easily. I like to think of it as the freddie star approach.
