This portable surface supplied breathing system is powered by a rechargeable, replaceable battery. It allows users to dive to 30 feet for up to 60 minutes on a single battery. The Smart Reg is synced to the compressor so that it pumps air at the same time and speed that the diver is inhaling to maximize battery life. The system will vibrate to alert a user when five to 10 minutes of dive time are remaining. The compact system weighs only 15 pounds, and it is airline friendly and positively buoyant without a float.
