hey lanny,booming is a semantic term for uh,shallow water suction nozzle uh,deployment.301 feet or further from any active watercourse here in cali.active watercourse being a fluid term. while it makes possible the use of equipment otherwise not allowed(within 300 feet),booming presents new challenges in adaptation. volume/pressures reduced at these distances from pump location,mean multi-pumps,viability of available deposit within reach of equipment/water available the major obstacle for me at least.spent a month on a nearby ground sluice(spare time) two pumps, one 370 feet downhill to a 4inch suction nozzle,smaller pump sidehill from a swimming pool for supplemental/blasting water.google search midwest prospector supply,watch the dryland dredge nozzle video there,that one gave me some ideas/headstart.currently debugging a 600 foot gravity pressure line for these purposes,runs my 2.5 nicely,but needs a few upgrades for the 4.btw love the pics you post.is that a mini 6 dredge or a 5?bear stinger looks good 2.luck
