I had to look for an alternative to a rubber weight belt, as I have wasted the second one. The reason is, because I am a bit overweight I have to pull the belt with 9kg's of lead quite tight otherwise it slips over my hips. It then starts to tear at the hole where the buckle is clipped in. I made up a belt with an old buckle, a piece of car safety belt and a short piece of 20mm spear gun rubber. After ±20hrs in the water I do not think I'll need to buy a rubber belt again.
