Blowback
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.
