Available from my dive equipment collection, one(1) Scubapro MK 10. This reg was serviced in July of 2021. Also included is a Scubapro G250 serviced by an authorize Scubapro tech and upgraded. Set includes a 5000psi Scubapro pressure gauge and inflator hose that probably fits a Scubapro Air 2. Also included is a used reg bag. All of this equipment is used and should be checked out by an authorized service tech before being used.
