Easily trim from 10″ wide down to 8″ wide using the pre scored line on the back of the mat.
Built from flexible thermoplastic rubber, the mat can easily be rolled up to let you rinse out the concentrate that you have trapped. The concentrate rinsed from the matting will contain most of the gold accumulated during the run and is now ready to be panned and separated.
This kind of riffle increases the turbulence behind the riffle, which agitates the sand bed, improving gold recovery.
The ‘V’ shaped riffles work very well for catching fine gold.
Our square riffles catch small nuggets of gold exceptionally well between its larger grooves.
