What is Downrigger Blowback?
Simply stated, downrigger blowback is what happens to the downrigger weight when you pull it through the water behind your trolling boat. As your speed increases, so does the horizontal distance between the downrigger weight and your downrigger. The faster you go, the farther the downrigger weight is behind you. The farther the downrigger weight is behind you, the shallower the weight is.
You know one of the things I think that’s really crucial is controlled fishing depths and the way I think I have the most control on my electrical downriggers. I’m actually running the new cannon 16-pound downrigger weight and the reason I run the heavier downrigger weight, especially in this situation is I don’t want that downrigger blowback and what I mean by downrigger blowback is the speed will actually push that downrigger weight way back.
You have more control depth with this heavier downrigger weight versus any other weights out there. I really think that’s crucial so if you see in what I was talking about downrigger blowback is you can actually see that I’ts a lot more vertical. Than a lot of times where you’ll see that line out at like a 45 that’s the reason why here on my Cannon Optimum downrigger it’s 67.
You know there’s only three or four foot downrigger blowback versus if your running a lighter downrigger weight. You might have eight or nine foot variance there so the depth you’re looking at is gonna be a lot more controlled, you know, the other thing I pay attention to not only on my fish hawk, but on my downrigger cables as I actually watch them.
I don’t want them drift into one side of the other, that means I’m fighting the current the straighter. I can keep my downriver cables the more bites. I’m gonna get.
Downrigger Blowback Chart
The following downrigger blowback charts provide you with downrigger 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.
Downrigger Blowback Calculator
As an example, the first chart shows that if you are trolling at 4 MPH with an 8 pound downrigger 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.
For a long time I was wondering about what size downrigger balls I wanted to have for my little boat here and some of you might find this helpful but right now I’m going 2.2 miles an hour and on my right downrigger, I have a four pound ball and you can see the angle of downrigger blowBack right there. I don’t want to guess what it is.
Compare that to the six pound ball on my left downrigger it has a lot less downrigger blowback than that four pounder downrigger weight. And this is at 2.2 miles an hour. But now if you throttle it up a little bit, you know and get up to say 2.5 miles an hour. You can see how that takes us out at two and a half two point six miles an hour.
Now you come back in that four pounder downrigger ball is this way back there and the six pounder downrigger ball is also further back. They’re holding steady pretty well. Now if you’re going to get down I’ll go to idle right here and pull all these these lines you know, there’s still a little bit of blow back there for the 4 and the 6 is about straight down.
So sometimes it can be helpful just to see the difference there is you’re trying to shop for downrigger balls and I hope some of you might find that helpful. You know, by the way, you can see on the depth finder that the four pounder downrigger weight is just over 40 feet deep and the six pounder downrigger weight is about 50 feet deep, so that’s noteworthy too that there’s 10 feet more of depth on this one and you saw the difference in the back even if it deeper.
So, hopefully some of you found this helpful and you like this website.
