I mean, once I got the second (exh) check valve in place, it pumped water out like a fire truck. Or an X with a couple of bolts in the 1 inch intake Which means.I gotta come up with a shot glass style end for the intake to filter out all cept for -1/8. So.1/8 inch screened before entering is much more realistic. A flapper for the exhaust to the bucket that I connected so as to expel all water but retain heavies but alas, -1/2 intake was MUCH too BIG for them as both valves opened, stuck and failed. Here's some pics as I stumble my way thru the process. it pulls some.with valves partially blocked open with -1/2' rocks.ugh. With both styles of check valves (cone intake with 1/2 pound spring pressure and a HD flapper valve at exhaust.and if I work up a sweat.

Suction is provided by a wafer Styrofoam-like freeze plug style (obviously need to upgrade it to a leather 'seat cushion' wrap around.maybe even chamois?.) IDK With 2 check vales and straight water? You could flood a place real quick. And the same thing as a pro is a con as I had to shorten it to 5'2' as new hardware made it as tall as me! 6'2. Also, the last most precious thing you sucked up will be the first thing to dump out on the ground on it's way to the pan or bucket soooo. An angled intake (45/90) would help but still a major PITA (and not in direct point of contact with bottom as you can rarely see while operating it anyway.

Adapt by pulling less and raising sooner but still a PITA. Reaches where I can't.Ĭons: Dumps rapidly at the end of each stroke as no check valve. Disturbs only what I want, where I want and water is instantly returned as it flows out of the Super Sluice pan for con collection. Performance of original configuration of shrimp gun as adapted for gold recovery: Like pumping into an in-stream sluice, a bucket or a pan directly via 1 inch hose.would be so much easier. 045 gram picker!! It's my first and I'm sold! So.now.I want to take it to the next level. It handles like an Army Bazooka but first time using it, I find a. OK, so last year I buy a shrimp gun from a local going outta business hardware store for half off ($20). I started a project this week and I wanted to post what's happened so far.before the FOG syndrome sets in.
