Diving counterweight method

Diving counterweight method

If the weight is appropriate, your body should float vertically at a position where your line of sight is the same as the water surface, otherwise you must increase or decrease the lead block until it is in the right position. When doing the test, you can ask the dive guide or companion to help hold the lead block and adjust the weight.

Check one last time, and then exhale. At this time, if your weight is correct, you will sink slowly.
