I’ll throw down for The Mares Abyss also.
I shopped regulators to death and settled on the abyss.
Other than these I’ve only dived with the standard scuba pro rental gear before
investing in my own gear.
Even the low cost Mares MR12 ranger on my pony bottle breaths good.
Bang for the buck they are rugged, reliable, and well built.
I’m sure any of the name brand regulators will serve you just as well.
