I just saw the YouTube vid, it looks like bottom bucket holds water, middle bucket to catch dirt, then a screen that you load material in to hose off from water from bottom bucket. I can see how someone out there who has mobility issues could benefit by hosing material down, although places like the bear river in colfax and surrounding places that ban any form of motorized pumps it might not be a good application. Gold ringer Steve, have you offered these for a free trial to people who might be interested? My thoughts are market this to anyone who needs extra help in the mobility area, and maybe offer free trials, I would also be a tnet supporter so you can legitimately advertise. As a former small business owner I would also look at the criticism as constructive and maybe when speaking about your product explain there are many ways to screen down but that yours is for a specific purpose. I know for a fact you will have good responses by that approach. Good luck and heavy pans
