Gloves	Keep hands clean while handling lead weights

Make the collar attachment
- Cut a short inner-tube loop sized to clip onto the neck collar ring (from Neck collar – Lead tube).
- Thread both ends through the 60 mm quick-release buckle and close it. This loop is only an anchor point, not a neck strap.
Thread the belt
- Pass the 60 mm belt through the buckle that hangs from the collar attachment.
- Slide on three 500 g weights, clustering them near the buckle end so they sit between shoulder blades.
Lock the weights
- Add the 60 mm slide stopper after the last weight to keep the stack from shifting.
Fit and adjust
- Wear the neck collar, clip in the belt, and snug so weights rest along the upper back.
- Add or remove 500 g weights to hit your target total; the same weights can be reused for depth diving.
