The 8" x 8" Jarvine Riffle is a powerful screened fluid bed riffle built to maximize fine gold recovery while maintaining excellent nugget capture. Designed and tested by Paul Jarvis (Master High Banker Builder), this USA-made riffle brings modern fluid bed performance to highbankers, dredges, and custom recovery systems.

Its screened design slows heavy material beneath the riffle, allowing fine gold to settle securely into miner’s moss or deep V matting instead of washing out. The aggressive zigzag riffle profile creates strong micro-vortexes that trap nuggets while resisting clogging from rocks and debris.

The 8" x 8" size offers increased coverage over compact riffles, making it an excellent choice for clean-up sluices, test boxes, and small highbanker builds where space and efficiency matter.
