Apeks Tek 3 First Stage Single Price £214 Pair Price £386 Apeks has developed unique 1st stages specifically for use on a twinset. We have now launched the new TEK3 1st stage regulators designed for use with twin cylinder configuration. The system benefits from streamlined hoses with little chance of accidental snagging & also enhanced ease of access to cylinder valves. Each 1st stage has 3 medium pressure ports & one high pressure port. They are balanced, cold water compatible & extremely robust. TEK3 looks great too. The regulator can be purchased in both a left hand & right hand version to fit both posts of your twinset for optimum hose routing. The TEK3 can be purchased individually as a left or right hand version or together as a pair. Usually you will find it is cheaper to buy them as a pair. Please see below for the mounted set-up. The TEK3 1st stages have been designed & tested for use with any Apeks cold water spec second stages. The choice is yours. We are sure this is a leap forward for extended range diving, wreck diving, cave diving, in fact any diving where twinset use is preferred.
