Mares XR finstrap retainer v1

thingiverse

If you have Mares fins and XR finstraps, this might be something for you. The finstraps are fantastic, but with the retainer bar in place, they can come loose. I've had it happen while diving, with the fin coming off and a team member grabbing it, which is unsettling. First, head to cave line, but one of my caveline lengths came off, so I decided to take on this project properly. So, let's talk about finstrap retainers. Remove the retainer bolt, place these behind the lugs on the fin, and then put the retainer bolt back through (check out the photo). Keep in mind that you're doing this at your own risk - I haven't tested it yet, and you'll need to decide for yourself if it's safe.
