For anyone heading to Belize, my husband and I and several friends used ProTech Belize Dive Shop for both a Nitrox course as well as for a liveaboard trip to the Blue Hole and other dive locations. We were very impressed with this dive operation. They had cutting edge/new equipment (we all dove with dive computers). The dive master, instructor, and staff were very helpful and attentive. We felt very safe and enjoyed everything about our trip (we had several new divers with us). Just a thought if anyone is looking for a recommendation.
