There are other good products out there with better compressors, but this unit seems to work well for hull cleaning and scuba
exploration via the dinghy
in small coves away from the boat. I strongly recommend getting a unit with the storage
tank and longer hose. The storage
tank allows a little extra time when the battery
runs out... a few extra, labored breaths to get to the surface. It won't just quit on you. FWY: When doing work under the boat, you'll use more air than normally used while just cruising around and looking at sea life.
One time while working under the boat, my battery ran out; the tank compressor left me with the feeling that I couldn't take in a complete deep breath and allowed a minute or more to get to the surface... it didn't just stop working.
