You then have to bleed all the air from the system ...
The power jet also allows deeper dredging because the power jet will lift material higher than a suction nozzle can push it. The disadvantage of the power jet is that the power jet and supply hose must be kept under water at all times. Therefore they do not work very well when working in shallow water. The advantage of the suction nozzle system ...
A power jet puts the highpressure water in just before the sluice box. A suction nozzle is best in very shallow water; a power jet produces better overall suction. Most dredges are power jets, but some smaller units, 3 inches and smaller are suction nozzles. I recommend the power jet.

The pump actually pumps only water, which is delivered to a venturi type device (called a power jet or a suction nozzle) which indirectly creates suction in a larger hose. The solves two problems.
Rated at 94 psi and 8120 gph this pump can actually power a 4″ dredge nozzle. You can also run at idle and use for highbanking. The only WARNING is that these pumps need to have a FINE SCREEN over the intake. They do not like sand and gravels. We have run ″ to 4″ dredge .

No one makes power jets like Proline. Rather than using a steel casting, we use a more efficient machine formed eductor. The result is a lighter power jet with better vacuum and easier priming. These power jets are popular with those building their own dredges or who simply wish to improve performance on dredges they already own. " Power Jet

the power jet with a hose clamp. The foot valve and hose assembly clamps onto the black pump intake on the pump. Take the time to make sure that all hose clamps are tight and the couplings are all snug before attempting to operate the dredge.
A dredge designed to work on flotation, with a compressor for underwater dredging, is almost always equipped as a power jet.
