You started diving with yoke style cylinder valves, but you feel the higher cylinder pressure available with DIN cylinders will be an advantage to your style of diving. Well this kit will allow you to do just that, shed the yoke and increase bottom time with this 300-bar (4350 psi) DIN conversion kit for all Yoke Atomic Brass Regulators. Also, Scuba divers who travel overseas will want to have a DIN adapter to convert to the tanks available at the local dive sites. The kit allows you to easily convert your first stage, if required, so you can use your own gear rather than rental gear! Most HP cylinders are made from steel, so you can also remove some of the weight from your weight system due to the lower buoyancy characteristics of the HP cylinder. For Atomic M1, Atomic B2 Sealed, Atomic B2 Swivel, Atomic Z2, Atomic Z2 Sealed, Atomic Z3 Sealed Swivel, and Atomic Z3 Swivel Regulators (see SKU's: ATMM1BK, ATMB2SS, ATMB2S, ATMZ2SS, ATMZ2S, ATMZ3SY, ATMZ3RY).
