Two already good suggestions. Tru-Glo also makes the Hip Shot whch isn't too bad either. I use a device--forget who made them, but it doesn't matter as they are no longer made. The Primos momo-pod, or Tur-Glo are about the only two I have looked at recently. The problem with the Primos sticks, and I have personally witnessed, and experienced this--the bottom section creeps/leaks down. Also if you ever get water from rain inside the stick--it can/will happen--it really causes them to leak down, and the stick becomes useless until you get things apart, and dried out. For this reason I have not purchased a newer generation 3 stick, becasue they have the same problem. Read the reviews on them--they are mixed. Over all--if you take care of the stick it should work fairly well, but durability--meh. They aren't cheap, but are made cheap--in my opinion.
