I am not going to argue, they broke because they are plastic, the part should be Delrin or metal, not plastic. The Halycon spring straps broke on dive number three I think it was, they were new and nothing smashed them, they were fresh from the bag. The warranty was not supported when I inquired and as I am out of state, the shop which is a well known one in Florida offered no assistance.
BTW, dive gear lives in a rough environment, so what we are saying is that Halycon dive gear has to be babied and handled gently lest it fall apart. Yeah, well, good luck with that.
I probably still have a pic of one of them, the other is on the bottom of the Gulf in 240 feet. Maybe get a "team" together and go retrieve it for an accident investigation. It is on the west side of the Oriskany near the bow. Jet Fins are great but they work best when you have one on both feet.

Here is the other side of the same Halycon spring strap, again, note the crack from the pin and if you look close there is a crack from the other pin also:
So, I dropped something on all four plastic thing-ma-jobs?
This happened three years ago, I now have the Waywardson straps and some DIY that I made copying Waywardson. The failure mode you can see begins at the small pins that are driven through the plastic pieces during manufacture. The one that parted company with me I cannot photograph as I said, it is not in my hands anymore. I did see it spinning away with a strap hanging to the side. I can only guess that the shattered plastic keeper came off and allowed the spring strap to get into a bind which either popped the wire from the fin or snapped it due to the load being asymmetrical. Dunno, all I know is they cost 70 dollars per pair and both straps of the pair broke and one failed and that was on the third dive with them and the other set did the same thing.
