No reinventing the wheel, but after 18 months of trial and improvement under demanding and tough conditions in the New England and Central West districts and a lot of interest from other prospectors I have demonstrated my device to, I am pleased to share this effective hand pump attachment to the gem fossicking and gold prospecting fraternity. I have been prospecting for 30 years and about two years ago, after being disappointed by the other hand crevice pumps on sale, developed my own. And it's light weight if you want to get into those deep gullies & remote creeks with a simple but effective kit in a backpack: Pan, my crevicing devise, your yabbie pump, short hose and bucket. Made from strong & non-corroding materials: PVC stainless steel brass silicone and high-density polyethylene components. Very easy & efficient to use, works at any angle, no tilting or removing the nozzle after every pull of the handle to empty the yabbie pump into a bucket. Pull the yabbie pump handle up again and cycle repeats. Push the handle down and the charge is expelled and directed into the outlet hose via the other simple flap/reed valve and then into the hose that is connected to your catchment system. At the same time, the vacuum created in the outlet hose is sealed off by a simple check valve. Place the nozzle into the crevice, pull the yabbie pump handle up and the water/gold bearing gravel slurry 'charge' is drawn into the barrel of the yabbie pump. Leaves crevices and bedrock clean as a whistle, just like your Mum's Hoover cleaned the Axsminister ! Let me tell you about it: It adapts snugly and securely directly to your standard 50 mm yabbie pump with a single stainless hose clamp. I have had a lot of interest from prospectors I have shown the device to in the field, it does what it's meant to do so, given the interest and its effectiveness, I want to see what response there is and the demand that may exist. Yes, that's right, I have decided to produce a few units of the robust, serviceable and most importantly, very effective hand operated crevice pump device that I have developed over the past 18 months for my own use.
