The Proline 2.5" gold dredge, the most popular 2.5"
suction dredge in the country. Just a few years ago, all 2.5" dredges
were floated on innertubes. Most of them were available only with a
suction nozzle to provide the vacuum and none of the 2.5" dredges were
capable of driving an air compressor. This all changed with the
introduction of the Proline 2.5" flare suction dredge. This was one of
the first 2.5" gold dredges which was mounted on sturdy polyethylene
pontoons, rather than the puncture-prone innertubes. This was the first
dredge of its size which used a flare and it came standard with a power
jet, which was much more powerful and easier to operate than the suction
This dredge has been redesigned to
create a lighter and sleeker dredge without sacrificing strength. The
dredge frame has been eliminated for weight savings and has been
replaced by a front and rear assembly which mounts directly to the
pontoons in a similar fashion to our 2" dredge.
The pontoons are all new and are capable of handling swifter water if
necessary. They are molded to be slightly thicker and incorporate larger
inserts than the previous pontoons for increased strength. These
features made for a very stable, powerful, and usable machine.
The sluice box still has rolled edges like the larger dredges, and is
designed for maximum fine gold recovery as well as easy clean up. This dredge uses Hungarian riffles, which are designed to develop a strong vortex or "eddy" when subjected to higher water speed. This dredge builds a stronger vortex behind the riffles to hold the values better, plus it doesn't have the tendency to load up on low grade material that other dredges have, leaving the riffles unshrouded to do their job more effectively. We use "Nomad" matting in this dredge for the full length of the sluice box. This combined with our unique one-piece classifier and riffle design has resulted in a greatly simplified sluice box and easier cleanups.

The dredge can now be powered by two
completely different engine/pump combinations. The first option is for
the unit to be powered by a 3.5 horsepower Honda engine and our HP 200
pump. This combination makes for a very powerful small dredge. In
addition to being one of the most powerful pumps of its size on the
market, our HP 200 was designed to be capable of driving an air
compressor to support more active underwater mining.
The second option is to power the unit with the 2.1 horse power Honda
engine and our HP 100 pump. This is the same engine and pump used on the
Proline 2" equipment and develops fairly good power on the 2.5" dredge.
It is considerably smaller and lighter, and requires less fuel to
operate, which makes it ideal for those looking for a little more than a
2" dredge. It cannot run an air compressor but most people do not use
air compressors on dredges this small. You also will not be able to
operate as deep as the original package, again not an issue unless you
are going deep with an air compressor.
