I picked up my clam gun from Fred yesterday and a couple of friends picked up a couple from him too. We used them today and limited in very short time. Me and my two friends were very impressed with the performance of the guns. The way they are designed they slip into the sand with ease. The big benefit is when you pull the tube back out of the sand. With a vent channel running on the outside of the tube it breaks the suction on the bottom of the hole you are digging. So instead of pulling on a suction trying to retrieve the gun and clam you lift only the sand and clam. That makes it twice as easy. Any body with a bad back should be using this gun. My group is sold on them.
