Extra Pocket Scale: This Pocket Scale allows you to weigh a maximum capacity of 200g and readabilities of 0.01g to provide you with an accurate and precise weighing session during your gold panning. Productive Gold Collecting: The riffles are built-in to create water turbulence in the sediment channel. In addition, they will trap gold flake and small gold flour in the pre-installed woven vinyl miner's moss. High-Quality Aluminum Alloy: The compact 36" sluice box for gold recovery is made of high-quality aluminum alloy. It is highly durable and rust-proof, so it will surely withstand the harshest surroundings. Effortless Use: Everything can be packed up in your backpack, ready to deploy. All you need to do is make sure your sluice box is level in the field. The sluice box will be locked rigidly in the stream when it opens, so it can't be swept away in currents. Portable Design: Our sluice box is 36" Length x 9" Width x 2.6" Height. Lightweight aluminum box construction and carry handle design make it easy to carry.
