The lobster squeeze bag is the easiest one-hand operated collection bag available, with one hand pull the lower handle towards the top handle and the bag opens with a small amount of pressure, release the handle and the bag will spring to the closed position. Bag is made of durable nylon upper for easy entry of spiny lobster, with a mesh bottom that will keep the "bugs" in the bag when you re-open it for the next lobster and drains rapidly once back on the boat or shore. Corrosion resistant hardware and handle mechanism for durability and long life make this one great collection bag for diving.
