16"x10.5" Jarvine Riffle

The 16" x 10.5" Jarvine Riffle is a high-capacity screened fluid bed riffle engineered for serious gold recovery in highbankers and dredges. Designed and proven by Paul Jarvis (Master High Banker Builder), this USA-made riffle delivers exceptional fine gold retention while maintaining aggressive nugget capture under higher material throughput.

Its screened fluid bed design slows fine heavies beneath the riffle, allowing gold to settle deep into miner’s moss or deep V matting instead of blowing out over the mat. The taller zigzag riffle profile creates powerful micro-vortexes that trap nuggets while resisting clogging from rocks and debris—making it ideal for longer runs and heavier feed rates.

With its larger footprint, the 16" x 10.5" Jarvine Riffle is perfect for full-size highbankers, production dredges, and custom builds where efficiency, consistency, and recovery performance matter most.
