What's the diff between a MK25/S600 and a MK/A700?
A huge amount of money more for a MK25/A700 and in reality not much more performance.
The A700 looks very blingy if that's your thing... its not a big seller here on Koh Tao because of the price... the S600 still sells very well... match it with a MK25 and it will deliver more air than you will ever need and at any depth.
A few years ago Scubapro did a test with 100 divers breathing off 1 x MK25 in a swimming pool at a depth of 3 metres and this MK25 delivered air to all 100 divers... very impressive. and has never been surpassed by any other reg out there on the market to date.
My two pennies worth... and yeah.. i am a Scubapro dealer... although i try not to be too biased
