Question DPV crotch strap

[stuartv]

Anyone know where to get just the "Y" bit in the DiveX 3 point tow harness?

I'm thinking about integrating the DPV harness 3 point system into a backplate's webbing

That seems like a lot of expense and hassle instead of just using the one from Cave Adventurers.

Or simply making one with 3 serrated tri-glides, 1 D-ring and about 2 meters of webbing …

Do you have a pic of one? That seems simplest and most cost effective...

There was a point in time I used a Swiss seat a lot.

There's no way I'd want to use that while diving with a DPV.

If I had no other choice, I'd use it but I wouldn't choose to use it.

It’s really simple. A 3 inch loop in the middle of the webbing and 2 inch loops at the ends. Size to fit, with webbing stiffness and color of your choice.

Few backplates have a pair of slots on the bottom, so if your backplate doesn’t, attach to the back of your waiststrap immediately next to your backplate.

You can see his pic. It is virtually identical to the Cave Adventurers one.

However, the CA one has the scooter D-ring sewn in, instead of held with a tri-glide.

Personally, the CA one is totally worth however much more it costs versus making your own like @Umuntu showed.

My experience with a D-ring held by a tri-glide is that if you actually use it for scootering, the tri-glide will gradually, slowly slip and the D-ring will work its way closer and closer to the end of the crotch strap. It is annoying, at the very least.

It's not like these crotch straps are consumables and you're going to be replacing it every year or two. For a piece of kit that works better and lasts indefinitely, $30 is a no-brainer, to me. I actually have one for each of my CCRs and one for each of my OC rigs.

Which is why I suggested using serrated triglides, which bite into the webbing and (help to) prevent it moving. But re-adjusting the loop length is a simple thing and would only need to be done after multiple dives. If it moves too much use thicker webbing and/or add a second serrated tri-glide to act as a stopper on the loop side of the crotch loop.

Personally, I enjoy a bit of DIY, and I’m often puzzled by the readiness to splash cash on really simple gear that can be easily made yourself. Some people enjoy shopping. Everyone is different and YMMV.

All valid points. I was thinking of trying the concept using tri-glides to see if myself (plus buddies) like it and if we all liked it, finding a seamstress to make ~10 of them for our dive group. Sure, we could spend $300-350 for 10 straps from CA for the group of us, or we could spend 1/5 of that and make a batch ourselves.

One small caveat is a couple of my buddies have colored webbing and would *prefer* their crotch strap to match... so they'll be DIY in the event they like the concept

I tried serrated tri-glides. None that I have would fit a double thickness of the webbing through it.

Have you found and use serrated ones that will accept a double thickness of webbing? If so, a link would be appreciated?

With a regular tri-glide, even with a second one to backstop it, a single dive with my Genesis scooter being run hard would still move it enough to require readjustment.

I think sewn is better, period. CAN'T move, versus "shouldn't" or "probably won't" or "hasn't yet".

If I had a way to sew my own, I would DIY it. But, I don't. And my time is worth something. All in all, $30 is well worth it (to ME).

Theres the problem! Send that Genesis my way, I'll replace it with a nice Blacktip. You'll never worry about too much thrust again!
