Try out one of our full face mask sets in the safety of a controlled pool environment. They are not difficult to use, but very different to conventional mask and regulator setups. Our sets come complete with regulator swivel, quick disconnect hoses and surface air valves. This is a good opportunity to simply have a go or try before you buy. The session includes setting up the equipment with your own gauges and first stage, adjustments, demonstration on fitting and removal, surface air valve usage, equalising and clearing techniques. The session is free to purchasers buying directly from the Dive Centre in person. The fee is also fully refundable if taken as an experience session and a unit is subsequently purchased
