Please note that the proportions for this hi-banker are pretty important to get the correct water speed for the catchment areas. The banker pictured is a combo set up for gold as well as Sapphires. If you're chasing Gold only use a sloped expanded mesh.







High Banker Species.

I have invited the "Canberra Connection" to drop over personally to inspect the banker and clarify any questions they may have.

For the many inquiries I have received, I've decided to put up some detailed measurements as a few are getting the proportions wrong, and are having to make amendments.

Keep to these proportions.... If you want, you can make it shorter by leaving the forward grid out. (Gemstone only section). Make sure you leave the skid area at the back of the box at least 500 mm long, to gather enough water speed for vortexes to form at the first riffles. My advice would be to make the box the same length as shown, as this one works perfectly in all situations.

I use 2 recovery systems. "First", for gold only I use standard sloped expanded mesh. "Second", for all areas that have any possibility of containing Sapphires and gemstones with the gold I use Catwalk vertical sided mesh. NOTE: This requires regular sideways agitation to settle the gems through the gravel.... Both meshes are as per dimensions shown and are interchangeable. I highly recommend the cut out crate section be used with both recovery methods.

Hope the pics are clear enough for you and don't hesitate to ask any questions you may have before your project begins. All the best and hope this helps your build.....Cheers, Wal
