Dutch dives begin the first weekend of May. Remember to come in for rentals the week before. If your new to our Shop, rentals are picked up and returned to the warehouse location in Shamong. The shop is never open the Night before a dive day. (we have to pack also) Prepare ahead, diving is not a last minute sport :) Dutch dives begin the first weekend of May.
