Scuba diving regulators are an essential component of your diving equipment, acting as the lifeline between you and your air source underwater.  Graveyard Hunters, Inc. has used gear for sale that has been acquired through trade-ins and purchases.  Prior to selling, all of our regulators are inspected, cleaned, pressure tested, ultrasonically cleaned and overhauled by our technician using original manufacturer’s parts.

All profits go towards our mission and buying gas and maintenance for the Graveyard Hunter dive boat.

Mares MR12/NIKOS Regulator Set
The MR12 first stage is the standard balanced diaphragm design. It is known for it's delivery of a constant intermediate pressure to the hose leading to the second stage.  Since the first stage delivers a constant pressure to the second stage, the second stage can be finely tuned to that pressure and it will breath easily throughout the dive. The MR12 has one high pressure port and five low pressure ports. The Nikos second stage is a no-frills down-stream design, very simple and very reliable.

TUSA TR400/IMPREX Regulator set

ScubaPro designs it's regulators, but they are manufacturerd by Tabata Corporation.  The Tusa (Tabata USA) Imprex 400 first stage was a Mk 10 clone. It actually shares the same parts and part numbers as the SP Mk 10, and had only minor cosmetic differences. TUSA used the earlier reversible seat, which was more durable and had the advantage of being reversible if one side wore out.
