+10 on the CMC Rescue products. I learned of them from SWAT and Technical Rescue buddies. I then made some of their harnesses and rescue equipment standard on my tower crew's vehicles in the old job. Not only is their stuff top notch, it is comfortable (related to others) and service was second to none.

Live bait, whew . . .
Looks like those guys should have an extra buoyant PFD. Just to haul the weight of those big stones with them. That looks like a way to become dead bait. My hat is off to them!
