NB:  I don't get to log on frequently (with school being out for the 
summer), so my appologies if this has already been discussed to death.

Hi all!
	John Heimann poses an intersting question...

->More tension on the line when shooting the bag?
->Use even heavier line?

	While both of these might work, they might not be all that 
pratical.  If the diver in question has their buoyancy perfected, then the 
extra time that it takes for the liftbag to hit the surface from a free 
swimming (ie, without the diver having direct contact to any solid support 
- ground, ship, huge sea turtles 8-)  might not have as great an effect as
for someone whose buoyancy control isn't quite figured out yet.  As for the 
heavier rope - it's a greater load to carry around.
	Why not extend the neck on the liftbag by about 10 cm or so and put 
a couple of small 50 g masses on the lowest part of the neck to keep it
submerged?  That should give the neck of the bag sufficient moment to keep 
the neck submerged.
	Hope it helps,

	Pete
