For sure, 12v would be useless if you were in the water all day.
I'm thinking I need 60 to 90 mins of runtime.
Good advice on looking at ebay, etc. I may give it a shot.
I'm curious, what first stage pressure do you run the compressor at? I presume it just cycles on and off if you aren't drawing enough?
