I know what they are trying to exactly do. I did buy the Apeks when they came to the shop last week. But normally I use Abyss regulators, and in my last three classes at least one person form each of those classes bought an abyss. I also had one person but a transpac which I use in the pool. And another buy a halcyon bc which I used on their check outs. SO they act like they are doing you a favor but n reality they take a little lose on you and make it up with everyone else
