DirDirect :: Regulators & Hoses :: Single Tank Regulator Sets

Safe • Simple • Streamlined - Whatever your diving style.

Our single tank regulator sets from world-leading manufacturers have the recreational diver's safety and comfort in mind with outstanding performance and excellent streamlining.

Standard hose sets: Standard regulator sets consist of a 1st stage regulator and 2 second stage regulators - one of which is an 'octopus' on a slightly longer hose (to donate to another diver) and generally identified as being yellow. Hoses on these sets are standard length, used world-wide by recreational divers. 

Long hose sets: Specialised "long hose" sets utilise a 5' (or preferably 7') long-hose for the primary 2nd stage (which a diver breathes from). The diver then donates this working regulator to an out-of-air diver and switches to a backup regulator generally under the chin, on a 'necklace' and shorter hose. This replaces the traditional concept of an 'octopus' always ensuring a working regulator is donated in a stress situation.

Whichever setup suits your diving style and training we're here to help you. You can  Try Before You Buy some of the select rigs if you contact us at Underwater Explorers or visit us for a free dry workshop.
