Your basic Gold-N-Sand hand pump with removable viewing scope allows you to see what you snipe. A new item so no videos yet...the scope is designed to reach underwater snuggled up to your gold sucker, but not too close.
It really comes in handy when you are prospecting in the bedrock and need to take a peek at the gold sitting there. Put away the tweezers and suck it all up with the pump. "That's what I'm talkin' bout!"
