Our standard octopus lines are precision engineered to provide the same outstanding reliability as your primary Sherwood regulator. The Sherwood Minimus is the first regulator designed specifically as a backup air source. The Minimus has a uniquely designed mouthpiece position that allows you to give extra air to divers at your left or right-hand side. Because this Octo is 35% smaller than most standard octos, you are provided with a lightweight, less bulky dive. Rugged, dependable, and affordable, the Minimus is the very first regulator specifically designed to function as a backup air source. Constructed of strong, durable materials, the compact Minimus provides you with the breathing performance of a primary regulator.
