The Gemini is a new star among alternate inflator regs, and for good reason. This backup breather turned in some of the best ANSTI breathing machine scores in August's review of inflator regs. In fact, it was only one of two units tested that was able to survive all four of our breathing machine tests, and in real-world use, test divers reported it breathed as well as some primary regs. It also does a great job as a BC power inflator, thanks to a slim profile and diver-friendly buttons that make ascent control smooth and easy. All in all, a well-deserved 2007 Best Buy. $200. www.sherwoodscuba.com.
