"That's the first time I've seen the 540 catch it properly!" Have you had problems with this particular 540? I wouldn't want to hear this comment about a piece of my equipment that's in service!

Fair comment. Actually, it wasn't me who said that. We have some 540's for teaching/demo purposes, but our "standard" is T3WP's. The guy who made that comment is an extremely experienced instructor and rescuer, and I believe he's had issues before with 540's being slow to catch shock loads. I don't know for sure, and can't really comment further because I don't personally use the 540 by choice.

Can you add anymore details i.e. what was the weight of the load? (600 lbs?), how much was the drop and over what length of line? Cheers

Hi - that's a tough one to answer. This was a live demo given to cave rescue students during training, and obviously wasn't intended to be a scientific test. We didn't weigh the rock, but it took 3 people really cranking on a 3:1 to lift it off the floor. Therefore I'd say it was probably about 400-500lbs (~200kg or so). The pit is 120 feet deep, so the length of the line would probably have been about 100 feet (30m) or a little less. Hope that helps you out. Cheers!
