If I troll with 40 jets what is the dive curve for them? Also how does speed and type of line figure into this? If I see fish on sonar at 15 feet down how would I set my lines are far as running above them or right on them?

This should be close, line size will effect this
Try to present a few feet above marks your targetting
That looks like a Dive Curve for #40 Tru-Trips.... Luhr Jensen Jet Divers run a much lower Curve....meaning it takes a lot more line. Type of line does figure in slightly...Here's the Dive Curves for both if using 30# PowerPro:
Speed can affect the depth, higher speeds will give you deeper dive, but these are very consistent in the dive curve from 1.5 to 2.5... Smaller line will give you greater depth, larger diameter will give you less depth, but only by a small percentage.Code:#40 Tru-Trip #40 Jet Diver (Top Hole)

If you're pulling big boards, there is a slight rise in your tow line from the board to the boat. That itself will account for a couple foot of change in the water column. If you're marking fish at 20 feet, I would set my first line at 18-22 back, that's checking for high fish you might not see, or fish that want to come up to hit baits, usually in cleaner water. All others lines I'd set at 35-40-45, then see what hits. If all your fish start coming at 35 and 40, reset your other leads to that. Try a 37 or 38, splitting the difference...
Couple key things to remember: BIG difference in dive curve from a #40 TT to a #40 JetDiver... also, pull baits above the walleye. Suspended walleye won't usually go down to get a bait, they feed up. Bottom walleyes can be different.... they'll pick a bait off the bottom, but we're not usually trolling for bottom dwellers!
So, once you figure out the depth they want, then the color and type bait, along with the speed, then match it up with their preferred direction - you'll be whackin' em! Experiment a little each day, and pay close attention to what leads are catching.... after the first few fish, hopefully a pattern will start to develop.
Good luck!
Sorry.....i forgot to mention I'm pulling #40 Tru-Trips.....
Captain Eric covered your question pretty well.As for setting a lure at a depth to try and catch fish showing on your sonar.Your sonar unit may be a foot or two below water level when mounted at bottom of boat so the fish marking can be a couple feet deeper than marking if directly below boat.But if fish off to the side will be shallower than showing.So it is a range.Fish in clean water can come up 10ft or more to grab a lure.It is less in dirty water.That is why you want to cover the water column initially as capt Eric said.
Thanks for the awesome feedback. Anyone know the divecurve on bandits?
When running bandits it's no jet just bandit correct?
all this is great info. keep in mind they are giving this to you based on the fact that you have calibrated your reels. so when your reel says you're 85 back you're actually 85 back.
