how can i fix weight belt on hips?

[shekh]

I need not much weight, about 3kg seems optimal. I dont use wetsuit.
The belt is easy to tighten around the belly, however I feel more comfortable when it is lower, around pelvis bones. The problem is, it tends to move out of its place very soon ending up on belly. I started to search and found very little. Basically there is practice to use "brace belt" - but I am not sure what it feels like when I wear only basic swimming pants.
I have an idea to create a system like climbers use. What people are actually using? Most pictures show belt around belly, but isnt it adversely affects breathing?

Use a rubber Marseilles belt and do it up TIGHT.

As you go deeper (upside down), your suit shrinks but the tension in the belt will keep it in place.

I have two rubber belts and tried both. One is of more soft rubber (actually made from car inner tire).
I made it quite tight, just before feeling pain. Not sure I want to go any tighter.

In fact the problem appears not from depth, but from doing ordinary moves.

Distribute the weight on each side and back if necessary.

It's not been a problem for me...

I think Sporasub makes a crotch-belt addition that might work for you I you still have the issue.

Addition like this one?

Thanks, this is what I meant by "brace belt". Have anyone tried it without neoprene suit?

You could try a vest like these:

Lots of different designs out there.

I used to dive with a belt that kept sliding down and had a very cheap solution that worked quite well. I had a bit of string folded double and tied the two loose ends together, forming a loop. I stuck the belt through my string loop so that the string would hang down the back roughly near the builders crack. I would retrieve the loop between my legs and stick the belt through the other end of the loop and fasten the buckle. This effectively acted as a crotch strap bracing the belt in place. Suppose you can call it a freedive belt g-string. Occasionally the string would get you in the sensitive bits which wasn't conducive to relaxed diving.
Glad to say I now have a Marseiles belt and works fine, but like you the damn thin shift from time to time no matter how well my weights are distributed or how tight I have it.
If your anatomical mechanics keep dislodging a rubber belt from your hips, you will might have to devise a crotch device. You said you don't use a wetsuit so why don't you try diving with less air in your lungs. There might be a tradeoff benefit in being able to relax more if you don't have to fiddle around with weight belts shifting around which might yield longer safer dives even with less air.

Happy diving

Thanks for reply, interesting suggestion.
Yes I can have some limited fun with empty lungs but it is not equal trade for me. I prefer to keep maximum air and the weight, and to improve the weight so I spend more attention on something else.

Now I have this thing. The structure is essentially the same as seat harness except the force is applied differently. The two side weights are connected with help of velcro. This is ordinary textile velcro, not anything titatium dual lock. So it cannot hold weight by itself but perfectly prevents sliding in any direction. I glued the loops part of velcro to the weights. The weight belt itself has nothing special and is dressed on top.

Overall I am very satisfied. Everything is perfectly fixed. None of the belts has to be tight. No moves are restricted.
Yet to be tried in water.
