 GSP Gold Syringe II. This Crevice "Hopper" Dredge comes with the same Model 625 Power plant and has enormous suctioning power. Down pumping discharges water out the top through an anti back flow relief valve. Large capacity "Hopper" holds a pan full (24 fl.oz.) of suctioned material over 5/8 inch diameter. 

    Anti back flow valve housing is compatible with 1 1/2" I.D. hose, (available for an extra charge) and can be fitted with the 300 or 800 Micron "Specimen Bag" Kit to help stop any unsettled material from being discharged, and as the hopper tops the 10" fill mark.

   Gauge tested, the Gold Syringe equipped with 24" of .7 I.D (1/2" PVC Pipe). pipe spiked well above -10 HG, and with no vacuum leakage! An improvised nozzle with classifier screen could be used to increase the foot print thereby drawing more material up the pipe per stroke and into the hopper.

   Removing the #1 anti back flow valve and plugging #2 Anti back flow valve would allow the Gold Syringe to be used to " Hydro-Jet Fan" over burden on bedrock until a crack or crevice is exposed and can be suctioned clean with help from the Poly Flex Pipe. 

     Minor classifying can occur if clean water is flushed through.
