I have a great portable 2inch dredge for sale. It has a 3hp motor and and spare 5hp motor. It breaks down to the point most of it fits in a back pack with a small frame that carrise the motor. It floats on a inner tube so no big floats to pack in. I've packed this in several miles to get to some good gravel. The entire thing works great and I've moved a lot of material with it.
