This design feature traps all the material but allows the water in the cylinder to drain out.

During use, the material will form a rudimentary gravel & sand filter at the bottom of the tube instead of falling out the open end of the nozzle. The proprietary internal nozzle flap valve will trap all valuable material as it travels down the lower surface of the piston's internal wall. As a result this valuable material would be the first to be lost during transfer to a sluice, bucket or pan with other types of open ended hand dredges offered elsewhere. Second, heavier material such as gold or gemstone material will drop first from the water suctioned into the cylinder.

The first and foremost reason to use this device is the large material collection and holding capability. > Supplied with an adjustable position right angle auxiliary grip handle. > Supplied with a custom, detachable 8' x 1½' nozzle.

> Capability to perform multiple suction strokes prior to emptying. > Uses a flap valve to trap material and provide minimal loss of collected material.

> A collection chamber may be attached for added volume. The more loose material available to suction - the better the FATBoy will perform ! Under the right conditions two or three strokes could fill this unit to capacity. The FATBoy has been expertly manufactured using a number of proprietary design features found in the more advanced FissureMan II and GOLD-N-ROD models but with the capability of mass material collection! This tool will allow the prospector to collect large amounts of material with every cylinder load.
