Regulators! One of the most important pieces of equipment a scuba diver can have. It allows you to breathe safely underwater and owning one means divers can know what their regulator has been through and the knowledge that it has been properly serviced. Regulators are usually sold in three parts: 1st Stage and Primary together, an Alternate Air Source & a Submersible Pressure Gauge. They're usually purchased together as a set, although the parts can also be bought separately. You will need to choose the coupling method to link your regulator to your cylinder valve, either DIN or A-Clamp. The choice of which is up to you as most dive resorts will supply cylinders to fit either configuration. DIN is the safer option which traps the O-Ring inside the valve and can withstand higher pressures, but some more remote dive centres around the world may not have suitable valves, so you may need to bring an adaptor. All regulators will work in warm waters, but if you plan on diving in colder waters (below 10°C), then you should select one that is cold water rated with an environmental seal or similar cold water system. Remember, with most regulators, you will need to have them serviced every year, no matter how much you do or don't use them. We stock a large range of diving regulators and accessories from top brands such as Apeks, Cressi, Mares, Aqualung & more.
