This is the OG we recommend when four divers are part of the plan. Best for: Three- and four-diver crews, heavier breathing demand and maximum flexibility. Honda gas engine Dual-head direct-drive compressor Recommended for four divers Your experience may vary. Air demand changes with depth, conditions, exertion and how hard each diver breathes.

Made for Real Boats and Real Dive Days The OG combines a time-tested design with practical details that make it easy to own, deploy and support. 01 Air Stays on the Surface Keep bulky scuba cylinders off the deck while divers receive air through individual hoses. 02 Oil-Less Direct Drive Brownie’s direct-drive compressor design eliminates compressor oil and keeps the powertrain straightforward. 03 Quick-Release Connections Brownie’s QRS fittings make hoses and diver equipment fast to connect, disconnect and organize. 04 Refuel and Keep Diving Bring extra gasoline and continue the day without waiting for a large battery to recharge. 05 Equipment for a Crew One floating platform can support multiple divers when configured for the conditions and breathing demand. 06 Parts and Service Support Replacement parts are available, and Brownie’s service centers can support maintenance and repairs. Where will yours take you? One System. A Lot of Reasons to Get Wet. Boating & Yachting Inspect propellers, running gear, intakes and hulls. Lobster Diving Spend the season exploring with an appropriately configured crew. Commercial Projects Support marine research, inspections, maintenance and underwater work. Family Adventure Share the underwater world with trained family members and friends. Preparation matters Train, Plan and Be Ready Breathing underwater involves inherent risk. Proper instruction, maintenance, dive planning and emergency preparation are essential. Get Properly Trained Divers should receive appropriate training, follow current Brownie’s instructions and stay within the limits of their training, experience and equipment. Every diver should remain prepared to make an emergency ascent. Consider Independent Backup Air For dives beyond a depth at which a diver is personally comfortable making a controlled free-swimming ascent, many experienced divers carry an independent emergency breathing source. Spare Air kits can be selected in the Safety Bundle or purchased individually. Prefer a different power setup? Explore More Brownie’s Systems The OG is our classic gasoline platform.

Explore Built-In Systems Frequently asked questions The OG FAQ What does every OG include? Every OG includes your selected compressor and engine, the floating system, intake and flag assembly, standard downline, equipment for two divers, two basic tow belts and one basic mesh gear bag. Which OG should I choose? Choose the Briggs & Stratton single head for the lowest starting price, the Honda single head if you prefer Honda power for a primarily two-diver setup, or the Honda dual head for greater airflow and the recommended configuration for four divers. Can a single-head system support four divers? Actual results vary with depth, conditions, exertion and each diver’s breathing demand. Four divers on a single-head system are recommended only for light breathing in extremely shallow water. We highly recommend the Honda dual-head configuration for four divers. How does the Safety Bundle match my configuration? When you select the Safety Bundle, its quantity and price match the total number of divers in your chosen configuration. A two-diver OG receives two sets, a three-diver OG receives three and a four-diver OG receives four. What comes in a Basic Add-a-Diver Kit? Each Basic Add-a-Diver Kit includes an additional divider connection, one 20-foot diver hose, one Brownie’s low-pressure regulator with whip and one basic tow belt.

Cummerbelts are temporarily unavailable and expected back in November. How long can The OG operate? Runtime varies with the engine, fuel supply and operating conditions.
