From what i read your friend has rices sized nuggets/pickers which would make them able to pass through about 10-12 mesh, for the most part and an 8 mesh screen most all the time unless its really long wire type gold. The friction will keep the cap in place and will easily release the cap with a gentle outward “pop” of the plunger.While i have not built my own dredge, i have run a couple and have thought about building one a time or two or improving an existing one. Some people prefer the cap to be tighter, and this can be achieved by wrapping black electrical tape around the top of the pump body two times. The cap is designed to remove easily so you can dump your material into a pan or bucket. The top rim of the pump is rounded out so you can remove and replace the leather cup without damaging it. When you are preparing to use the Quick-Sniper, just soak the leather cup for 10-15 minutes in cool water, then insert it back into the pump for ready use. The leather cup inside the tube is designed to provide years of effective service. If this tube is sliding too easily, wrap some electrical tape around the inner end, and it will be more secure within the Quick-Sniper.

The blue tube extending from the end of the nozzle is designed to pull out, allowing you to extend the reach of the tube about 4-5 inches. Then, after you have repeated this action a few times, pull off the cap and dump the contents of the pump into your pan or bucket.

Shaking the pump gently will transfer the heaviest of sands and gravel deeper into the cavity. Instead of pulling the handle and then ejecting the material into a pan or bucket after each pull, the cavity created inside the tube will hold your heavies, allowing water and the lightest material to swirl out and go back into the water before you pull again. This allows you to pump the handle four or five times before you need to take steps to collect sand and gravel. Inside the nozzle a short white plastic pipe extends into the tube. The “NOZZLE” of the Quick-Sniper is where the magic happens. The Quick-Sniper by Gold-N-Sand is a tool that uses some new ideas to help you collect the hard-to-get gold from heavy sands under boulders, in crevices, and behind obstructions.
