Scuba Choice Scuba Diving Adjustable Wrist Lanyard, Blue

To be honest I haven't had the chance to use it. But I don't think you can go wrong with something like that. I did however make it smaller to fit my wrist as I have tiny ones and that was real easy to do. Just shift the cord until the knot is outside the rubber hosing, untie it, pull out the string, trim the rubber hosing to a desired length (for me, it should just wrap around the top 3/4 of my wrist), and then finally loop the string back and tie the knot. Once the knot is tied, move it back into the center of the rubber hosing. And I'm pretty sure that with all the tugging I did while trying to get the knot back into the center of the hosing, it's unlikely to come loose in any situation.

Good Quality

I use this as a back up when holding my gopro in the water. I haven't dropped it yet but seems like it will hold up. It doesn't float and its quite large if you have a smaller wrist. Good for the money.

The rubber wrist in the closer adjustment is big. So if you have thin wrist you may have to cut a little bit of rubber to close it more and don't get it out without open it.

Anyone who is seeking a very simple and dependable tether for multiple products will find this to be a great product.

Perfect to carry cam or flashlight

Did not want to loose my computer as found it to become loose at depth, so used this and no worries. Tighten it up before my relector on drysuit and it kept all safely attatched to me!!

Divers can never have enough of these ;)

Good product. Well made
