SB Net Training (january 23, 2005)
Pre-dive briefing
* Safety first.
* Time-out sign ends the exercise.
Line cutters available at the now-net only to be used in an emergency. These nets are clearly visible but consist of almost invisible fishing lines. Do not try to turn around to look where you're stuck in the net. You'll probably only get stuck more. Just try to feel on what part of of your equipment the net is stuck.
If you can't do it with your gear on, just remove it. Integrated weights really make life interesting here. When you've freed yourself of the net do not attempt to put your gear back on while syill in the net! By the time you've donned your gear, you'll probably stuck in six or seven other places. Make a bundle of your gear, exit the net and only put it back on when you've the cuttercleared the net.
A line cutter is better than a knife. There's a bigger chance of cutting your buddy When you use a knife than when using a line cutter. Even if your're cutting away from him, you still need to get the knife close to him thereby increasing the chance to cut him. The cutting edge of the line cutter is inside and thus kept away. A knife can also be equipped with a line cutter but a knife is still a trade-off between resistance to rust and keeping an sharp edge. Where as a line cutter is cheap enough to replace if it has rusted after two years.
