The HOG PRO Hybrid BCD is designed to meet the demands for new, advanced or professional divers. Instructors and Dive Masters will find this unit a real pleasure with perfect positioning both underwater and at the surface with students or charter divers. The PRO incorprates the benifits of a Back-Inflate and Jacket style BCD in one unit. The Pro gives divers a very open and un-restricted fit similar to a BP/W. With features normally only found on much higher priced BCDs value is priority one. Great styling too!
