Subsurface dredge sluice setup

Just over 2 grams this weekend! Gold looks funny because it was 70% mercury when I found it. This is post burning it off. (with mask, outside, and standing up wind)

NICE pan ! I always screened my material to several sizes to help in my recovery of fine gold. and I always used a Rare Earth magnet to remove all Iron ore material . This helped my recovery of fine gold a lot ! And as stated before ,I rerun everything several times in the Winter !

What do y'all think about adding 10-15ft of hose to this thing? Considering this and then having the dredge dump out into a river sluice. Do you think the added hose will help or hurt or not make any difference for recovery? Also any other ideas increasing the sluice box size?

It all depends on the up grade of engine and
pump you chose to use ! But as is ,using your pump /engine with the added hose I say NO !

I do have an upgraded engine and pump off a Proline 4" dredge. 300gpm and 65psi. Currently using the engine/pump from a 2.5" high banker. 200gpm 35psi. Running her around 2/3 throttle.

Try not to be too impressed with my photoshop skills but thinking about something like this. might use a bolt and wing nut to keep the sluice connected to the subby. Thinking the sluice will have to be fully submerged with a fairly fast flow to be able to clear the large rocks. Be interesting to see how much if any gold it catches.
