DIR Regulators & Hoses

For the correct set of DIR Regulators you need to look for a set that are high performance, down stream, with a removable front plate, and with DIN type first stages that permit a good hose routing. Preferably a tried and tested design and ideally the same as the other regs in your system so that parts can be swapped between them.

The best regs out there for this job are the Scubapro Mk25 S600 regulators, closely followed by the Apeks DS4 XTX50 setup. Some diver will also use the Scubapro Mk17 First Stage or a set of Halcyon Regs. Please have a look through our selection and contact us using orders@aquanauts.co.uk if you have any questions, and a member of our technical team will be on hand to offer advice.
