20"x10.5" Jarvine Riffle

The 20" x 10.5" Jarvine Riffle is a production-grade screened fluid bed riffle built for maximum gold recovery in highbankers and dredges running higher volumes. Designed, tested, and proven by Paul Jarvis (Master High Banker Builder), this USA-made riffle delivers outstanding fine gold retention while maintaining aggressive nugget capture during long, heavy runs.

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 washing out over the mat. The taller zigzag riffle profile creates strong micro-vortexes that trap nuggets while resisting clogging from rocks and debris—making it ideal for consistent performance in demanding conditions.

With its extended length and wider footprint, the 20" x 10.5" Jarvine Riffle is an excellent choice for full-size highbankers, production dredges, and custom sluice builds where throughput, efficiency, and recovery reliability are critical.
