Gethooked Posted February 17, 2009 Report Share Posted February 17, 2009 How do you figure out the depth of your lure for how much line you let out. Link to comment Share on other sites More sharing options...
rocket500 Posted February 17, 2009 Report Share Posted February 17, 2009 Some lures, like the Mann's stretch lures, tell you on the box roughly how deep they swim at a certain speed with a certain test mono. Of course a line counter would be a help in knowing how much line is out. Link to comment Share on other sites More sharing options...
QAR Posted February 17, 2009 Report Share Posted February 17, 2009 a rough formula is [sin(A)](line out) where A is the angle in degrees the fishing line makes with the surface of the water. Sin is a function you can find on any scientific calculator. answer will be in the same units as your line out measure. The true depth will always be less than the answer due to bow in the line.

midwestexile Posted February 17, 2009 Report Share Posted February 17, 2009 There are also books of trolling depths for common lures, but they emphasize freshwater lures and they are not cheap. Midwestexile Link to comment Share on other sites More sharing options...

Gethooked Posted February 18, 2009 Author Report Share Posted February 18, 2009 I normally use umbrella rigs for stripers. I want to be far enough back from the boat yet cover all the water column. I fish in water 40 to 90 feet. Link to comment Share on other sites More sharing options...
epanzella Posted February 18, 2009 Report Share Posted February 18, 2009 How do you figure out the depth of your lure for how much line you let out. The best way is to find a cove with no current and a sandy bottom and experiment. You can feel the lure bumping the bottom and then you'll know. Make sure you're using the same line and the same lure. It's extremely important that you use your speed thru the water and NOT speed over the bottom. Your GPS will NOT give you speed thru the water and that's all that matters to lure depth. Make a chart for each combination and you'll KNOW where your lure is.

Ebbtide231 Posted February 18, 2009 Report Share Posted February 18, 2009 When we used to troll umbrellas and spreaders on mono it was a guesstimate. But! When we did hook up I'd try to hit the line, at the reel, with a sharpie marker. At least it was a reference point instead of guesstimating all over again.

I fish in water 40 to 90 feet. Switch to braid or wire. You will get about 10ft of depth for every 100ft in the water. "I just do what the voices in my tackle box tell me to do."

QAR Posted February 19, 2009 Report Share Posted February 19, 2009 I normally use umbrella rigs for stripers. I want to be far enough back from the boat yet cover all the water column. I fish in water 40 to 90 feet. You are going to have a relatively hard time fishing an umbrella in 90' of water if you want it to move laterally and you aren't just jigging it. You'll need it to be really heavy if the boat is under power. THat makes it really easy to hang on the bottom till you figure it out, unless you are over sand. You could possibly pull one behind a downrigger ball using a downrigger. I would rig it on a 3 way with a heavy sinker on something like a 113 senator combo. Put a guess for a starting weight. Let the whole mess out behind the boat under power about 30 feet and look at the angle with the water the line wants to make at your trolling speed. Pull out a highschool geometry book and look up sine cosine and tangent and figure out how much line out for say 80 feet deep, and then mark the line with a sharpie. Adjust as per actual field experimentation. You'll run deep with the tide, and shallow against it. Link to comment Share on other sites More sharing options...
