I`ve also been looking at the Atomic B2 with the SS1 integrated octo. Does anyone use an Atomic setup? What can anyone tell me about the differences between the Dive Rite pacs and the Zeagle Ranger? My biggest problem has been finding a dive shop that will provide unbiased feedback or a shop that carries enough of the equipment so that I can try them on or test them out before I buy. Anyone with a suggestion for a dive shop with these options?
