I just bought a Micro Sluice 1 concentrator 'used' (used 5 times) with vibration motor, instructions, and all the goodies.... for a good price.
Seems decent based on everything I had read prior to purchase.
Anyone had good or bad experiences with this unit? I plan on using it for concentrating classifications that range from +30 to 1/8"... (smaller classifications get the Blue Bowl treatment).
This is the model: Micro-Sluice 1
