Let's face it.  When working around so much precious metal, some polishers are tempted supplement their income with your gold.  Take away the temptation.  The WhirlWind Grinding Hood, when used with a good dust collector (like the Super WhirlWind Jr.), makes losses a thing of the past.  100% thief-proof, grinding collection cannot be circumvented.   The WhirlWind Grind Hood has a built in light and a special Plexiglas view plate.  With a proven track record almost of almost 10 years, the WhirlWind Grinding Hood is time tested to be the most efficient grinding hood ever made.  No other hood even comes close.
