You need a belt like the SCUBA weight belt for a secure dive. Diving comes with a lot of inherent challenges and you’re going to an environment where humans don’t live. The belt is well designed and has five pouches stitched into a webbing on it, so you decide the amount of weight that will be comfortable for you. The good news? The pouches on the belt are porous, so they drain quickly when you are out of water. Your belt could be equipped with this snap hook or this Keep Diving Diving Compass.
