It's important to look at WHY you want a certain type of gear. Example: You want a back inflation BCD. Why? Back inflation BCD's are not my recommendation for beginners. The buoyancy or lift is behind you, which has a tendency to push your face down into the water while at the surface when the jacket is fully inflated. In an emergency situation, when you inflate the BCD totally, face down is not a position you want to be in. To try and remain face up, it requires a bicycling move with your fins which is very fatiguing in a very short period of time. The reason we recommend the jacket style is because it will hold you vertically out of the water very easily making it much more comfortable at the end of a dive.
