The Best BCD Power Inflator

By Ben Knight on 07 Dec. 2016

The Best BCD Power Inflator Another fantastic bit of dive kit from Northern Diver. I have always used and been very impressed with Northern Diver BCD’s and I really like the integrated power inflator and scuba alert horn module. I find it very handy to have an underwater sounding device built into the inflation unit. I also have the Northern Diver Sea Harrier wing, for my twinset and due to an unfortunate boat incident, the primary inflator got damaged. Therefore I was extremely pleased to find (on one of my regular ND website browses) that you can now buy this great bit of dive kit separately. Thanks Northern Diver, what would I do without you guys..
