Electric 2" Gold Dredge: Hose SIZE MATTERS... but HOW MUCH? Efficiency measured with good results!

I tested suction with a 5 meter long (16ft) length of 2" dredge hose and several different sizes of pressure hose from the pump to the dryland suction nozzle. The results were surpsizing, leading me to change my hose size recommendation going forward. Will this low hanging fruit allow future larger 12v gold dredges to be build without any additional power required? I, for one, can't wait to find out!
