The four legs at each corner of the dredge lower into the water when you are at your dredging spot to give you stability and anchor you to the river or sea bottom. This dredge is pretty easy to get in and out of the water, coming with it's own trailer and winch. I have used this dredge as time has allowed and when you're on the gold it certainly gets it out of the river!Safety features include a second electric, hydraulic motor and pump in case the main one fails, to keep you operational and get you back to shore.
