A Lobster Hotel is a must to make the most out of each dive. These are basically glorified collection bags with a PVC gate affixed to one end, allowing the diver to deposit the catch one-handed without having to open anything. The plastic flange acts as a barrier, keeping the catch secure while the dive continues. One word of advice: Make sure the zipper on the other end of the bag is zipped shut before descending. It is particularly irritating when, after making the catch and thinking it is deposited securely, you see the bugger swimming away with a satisfied exoskeletal smirk.
