I have a 2.5 inch suction dredge, I found the setup nice when I am in really shallow water yet when I got a foot or two down I spent more time wrestling with my hoses and it was hard to angle the tip to get around rocks etc. To remedy this I cut about four inches off the suction nozzle and bought five feet of suction hose. Connected the newly acquired hose to the crash box, then the suction nozzle, then the fifteen feet of hose that I had. Using the part of the nozzle I had cut off as my tip. I lost very little suction as surface depths and it works much better at depths greater than two feet. My only mistake it seems was to not clamp the five feet of hose at the suction nozzle connection. I got sucked into my work and did not notice it had slipped off. Basically I was moving material from my hole and depositing it 10 feet away without even going to the sluice box. Yes I know a duh moment....or hour or however much time and effort I wasted but lesson learned lol. Anyways to remake the suction nozzle I have been told all I have to do is get a one foot section of hose and put the tip on it at the suction end and I would be free to lift it out of the water as needed. I am not in a hurry to do so since I am pleased with my makeshift powerjet.
