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.
