We harvest clams several hours around low tide in 2-3 feet of water. The bullrake is a long handled basket rake with about 20 teeth. Raking underwater helps the teeth liquefy the sand and push the clams into the basket. There is a rope attached to the base of the basket and clipped to a waist harness that we wear, so that we can pull on the rake with our body weight and our arms. Once you get the hang of it you can tell what your rake teeth are hitting - clams, rocks, shell, how numerous, how large and even sediment characteristics. Bullraking is a kind of zen activity which requires little time to learn but a lifetime to master, grasshopper.
