Gould Engineering Bazooka Dredge

After building an infinity jet, I now understand why the simpler jets are produced. I personally like the efficiency of the suction nozzle, the tri-jet and the infinity jet, but like anything that is more complicated to build, it is going to cost more. The trade off to the cost of the more efficient jets, is …

Getting The Best Performance From Your Dredge

The suction nozzle does not have this shortcoming, if you get an air bubble, it will disappear as soon as the nozzle is put back into the water. The one small drawback to the suction nozzle is that the high-pressure water that drives the venturi jet has to be fed with a hose at the suction nozzle .
