Cindy,
Don't buy a rattler, you can make one for a few cents out of scrap PVC pipe and a couple of old marbles. If you want, I'll make one for you.
Everyone,
Reels are used when making penetrations in overhead environments. The use of a reel greatly increases your chances of finding your way out. Features a reel needs are: a handle, a sprocket which turns easily, a method of locking the reel so it does not turn, a method of securing the reel and a method of cliping the line off quickly. None of the clips should be suicide clips. A suicide clip is a clip that will passively clip to a line (meaning without your assistance). A reel is a very simple device.
As for rental of equipment, the dive shop has normal equipment rental. I do not know if this includes knives, shears, safety sausages, whistles, mirrors, reels or slates.
If anyone needs to rent any of those items please send a PM to me and I'll be happy to check on the availability. Keep in mind, we will not be running 16 reels at the same time, so there will be some leeway for sharing. In an ideal world, or if we were contemplating a major penetration each diver would need their own reel.
