I have a surface supplied air source that will maintain two divers to 60'.
It was built by the preeminent builder in the Florida keys and has about one
hundred hours on the motor.
The Teflon lubricated pump gets serviced at 5000 hours.It works well and
comes with two one hundred foot air hoses and standard regulators and diving
weights.
It would sit on the deck or in the dinghy. It is the kind used by the
commercial lobster fishermen in the keys.
If anyone is interested in purchasing from me as I no longer am able to
cruise please reply to this with any questions.
