This discussion brings up some questions.  In the twenty-eight years I have 
been diving I have never had occasion to ditch my weight and I am not sure I 
can come up with a reasonably probable scenario in which I would want to do 
so.  But, if I did want to ditch weight I wonder if ditching a light would be 
of much use.  A 14 AH battery has a negative buoyancy of 5 pounds.  A 7AH 
battery is actually a better choice for diving the wrecks in our neck of the 
woods and has a negative buoyancy of only 1 1/2 puonds.  It does not seem to 
me that that would make much of a difference in an emergency.

Questions:

Assuming you are diving with dry suit and wings, and are weighted correctly, 
under what conditions would you drop weights?

Under those conditions would a 5 lb increase in buoyancy be of much value?  
How about a 1 1/2 pound increase?

Safe diving,
Dale
