After years of development, engineering, and design the Maximus is back. A high-performance regulator built to withstand the rigors of the cold and the deep. Maintaining its storied history with the underarm hose, the Maximus will keep it low profile for the tightest of quarters. New powerful and edgy cosmetics will give the Maximus a leg up on all the competition. One with all the key features of previous models; the reliability you have come to depend on and the serviceability technicians appreciate. This Maximus however, comes with improved breathing performance, enhanced cosmetics.

Innovation at its best is the way to explain the function of the Sherwood first stage regulator. The first stage regulator incorporates Sherwood's dry sealed spring. This simple yet unique design has a flow-by piston that mechanically balances the air of the first stage ensuring excellent breathing characteristics at full or low cylinder pressures. Balanced flow-by piston design, which is a "fail safe" mechanism, with a patented dry seal internal mechanism to keep the intricate components clean and contaminate free no matter what kind of environment you dive it in, constructed from marine grade chrome plated brass for long life and durability.

The dry seal function allows the regulator is increase the intermediate pressure of the regulator without messy oils or grease as with more sophisticated designs. This added benefit makes the regulator virtually uncontaminated from the environment of salt, sand or chlorine internally, which makes it the choice of most repair technicians. The first stage is equipped with two 7/16" threaded high pressure (HP) ports and four 3/8" threaded low pressure (LP) ports for addition of gauges and LP accessories; this is one work horse first stage regulator. Tee - shaped design reduces regulator profile when mounted on tank minimizing opportunity to make-contact with the back of the head. First stage has a high capacity inlet filter for smooth delivery of air to the second stage.

The Maximus 2'nd stage regulator comes with a 41" (104.14 cm) under arm hose that reduces jaw fatigue and less chance to snag. This reliable downstream demand valve design has an external one touch performance adjustment, so you can custom tune your dive. The regulator is designed with a smart lever that relieves the load on the seat. Extends seats life while in storage. Regulator has a large responsive purge cover easy to use even when wearing gloves. The new Maximus is also Nitrox ready out-of-the-box and comes with an owner's manual.

Sherwood Octopus has been totally redesigned to provide outstanding breathing performance. The Octopus maintains dedication to rugged reliability combined with ease-of-maintenance. The Sherwood Octopus has been the overwhelming favorite for rental applications for decades because of its simple reliability. Regulator has a large diaphragm for optimal response to inhalation with a precision ground stainless steel cam and Delrin lever for smooth effortless breathing. The valve mechanism is a dependable downstream demand valve. The regulator is equipped with a large high-quality silicone exhaust valve that decreases exhalation resistance for easy exhalation.

The Sherwood Octopus has a high impact resistant plastic housing for rugged applications. The low-pressure seat is resilient silicone rubber for extreme reliability. The low-pressure hose has standard 3/8" threads with a 36" (91.4 cm) length. The Hi-Viz soft purge cover makes identification of the octopus regulator easy in an out-of-air-emergency.
