#kesn2 outlet size: 2.0' inlet size: 1.25' Prices start at $135 for a 1.5' Suction Nozzle. More to follow.Ideal for shallow water dredging - these dredge suction nozzles are precision manufactured by Jobe and Keene from thin-wall plated steel tubing with machined orifices to create maximum suction pressure. We also plan to check out an ancient tertiary dry river bed located above the Illinois River in SW Oregon and work the cemented gravels on the bedrock that has not been previously mined. A dredging buddy has converted his Keene Ultra-4 to use the H-F 4 inch nozzle in similar locations. This July I am returning and bringing in a modified Proline 3' high-banker, some crevicing tools and a 3' H-F nozzle.

Also I should point out that this nozzle drew a lot of interest. I guess I was more amazed at just how much fine gold remains in the cracks in locations 'high and dry' and well above where other dredgers were working. Once I got used to operating the nozzle and finding some effective valve and volume settings (this took some practice) I started finding fine gold producing a little over 3.2 dwt for just a full morning's operation. This was on Oregon's SF Umpqua River in a dry location well above the river's summer levels and on some well exposed bedrock about fifty feet back from the river including a site is where many miners park their trucks to unload their gear. One had used the nozzle for mossing and said it had produced fine gold.Īs for my experiences last summer I tried out a H-F nozzle with a custom 2-1/2 inch high-banker using the nozzle in a variety of 'dry land dredging' sites. Most had checked out the video produced by the manufacturer and all had used the nozzle in different applications including sniping and just cleaning out bedrock cracks in locations near and above current stream flow working the gravels and bedrock with a crevice blaster tool to flush out gold from the cracks. These were in places previously worked for years with conventional (in-stream) dredging but new to this method of 'dry' dredging. Nearly all said it was worth the investment and the nozzle had opened up new above-stream locations for dredging. Last fall we wanted other opinions on how well the nozzle worked and we asked customers (1) if they felt that the nozzle worked effectively and (2) what were the various methods and locations they had used their H-F nozzles.

Since we started selling the 'Hydro Force' suction nozzles we've sold several in sizes from 2 to 4 inches. Thanks for the replies and thought I'd share what we learned.
