  1. How often have I started a dive with too much lead? It ruins your buoyancy and makes the dive drudgery by ruining the “glide” between frog kicks as Jose so ably describes earlier in this excellent guide book. On the flip side I have often been diving with too little lead–often due to a new wet suit that has not broken in yet. Then you face the misery of not holding a good safety stop at the end of the dive. Avoid these woes by adding 3/4 pounds ditch-able weight for each AL 80 to compensate for the gas weight or better yet test it with a matching empty tank before the dive. You want this weight to be ditch-able in the event of an emergency so you can float to the surface. If you were to ditch ALL your weight it could cause a dangerous situation of rapid ascent.
