Blowback
Simply stated, blowback is what happens to
the downrigger weight when you pull it through
the water behind your boat. As your speed
increases, so does the horizontal distance
between the weight and your downrigger. The
faster you go, the farther the weight is behind you.
The farther the weight is behind you, the
shallower the weight is.
The following charts provide you with
blowback information for three sizes of Cannon
downrigger weights pulled at three different
speeds with no lures attached and with no
current. Current drag, water salinity and the use
of non-Cannon products will affect your actual
trolling depth.
As an example, the first chart shows that if you
are trolling at 4 MPH with an 8 pound weight and
you have 100 FT. of cable in the water with no
current; the downrigger ball is actually at a depth
of about 80 FT.
