Differences Between Back Inflation BCDs vs. Jacket ...

This instructional video illustrates the differences between the back inflation BC’s and jacket inflation BC’s. The jacket inflation buoyancy compensator will keep you floating upright in the water and is a little bulkier than the back inflation BC. The back inflation BCD keeps all the air in the wing behind you and in the front there is a harness style webbing system. It will be easier to remain horizontal while diving with a back inflation BC. There are advantages to each type of scuba diving BC, so your choice should be based on your personal preferences.
