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?
Shallow Bandits will run behind #40 TT's, but 90% of the time, if we're running Deep Bandits, it's no diver or weight.Quote:

Capt. Eric, pulling big boards and the rise in the towline will change how my crank gets into the water column by a few feet. My inside rod when attached to the release and down the towline I usually stop it a 5 to 6 feet off the water and use that 5 to 6 add
to the line out, is this to much? Just calculate it just a couple of feet and forget about how far my release is off the water?
Gene
When we fished with Pooh Bear charter,he had big boards.He does not calculate the release is above the water when he determines the lead for that rod.Usually,what happens,is that we get a bite on a rod that is further from the boat.When we reel that line in with a fish or not,we move all the closer lines out further.To take the place of the line we just brought in.Then we reset the line we brought in and clip it to the cord and that line is now closest to boat.
Your tow line is 5 or 6 feet above the water? Any way to bring that down? I don't compensate for that at all, because eventually my inside rods might become my outside rods, as they get moved down the towline....Quote:

One of these days, i'll get a video put together to demonstrate. Other than that, i posted before, and i'll say it again - open invitation to all - call me, if I'm here, walk down to my boat. I'll be more than happy to show you what i do and try to answer any questions!
I may be a bit over exaggerating but I usually let more rod line out to where it is just a foot or so above the water but just when its close to the side of the boat let say the first five feet of tow line it seem to be that five feet down to the water. I'll check it out.
Thanks,

I've always felt the published dive curve for the trutrip 40 is incorrect. Graph it in excel and you'll see what I mean. Since the trutrip #40 is my go to diver for spoons and big boards, I just ordered a Fishhawk TD to develop my own dive curve. I'll determine the true dive curve and will post it back to this thread if it's significantly different than the one Capt Eric posted.
I may be wrong here but a fish hawk td is about 3oz in weight. I would think if you pulled this behind any diver it will give you a false diving depth.
Won't it be like putting a 3 oz sinker behind your diver????
Not to mention the drag that thing is going have it.
To test a running depth, you set the spoon and diver back the distance you want to test. You clip the FishHawk TD to the line and let it go. When you see it ‘thud’, it has reached the diver. Trip it and reel in. Max depth will be the depth the diver was running.
I can't wait to see if there is any differences. I'm sure the unit reads it's depth and temp right. Just have a hard time seeing adding 3 oz of weight anywhere on the line not causing a depth reading to be a little deeper. I can see it not effecting dipseys as much but on a tt40 or 40 jet I can't see it not effecting it.
The Web says it's 2.7oz 3 oz sinker at 2.0 mph, back 50 ft will be about 22.......so that thing on it's own would get close to that. I just can't see if I had 40tt at 50 back already running in that same 22ft area that if I clipped a 3 oz sinker to the line and let it slide down to jet that the jet wouldn't diver deeper. Maybe I'm thinking about wrong
Hopefully others will have input
I have one of these, the issue is it reads depth in (5) foot increments. Some days I believe four feet can make a difference.
Fish Tales
The manual for the TD says it goes to the foot for ‘max depth mode’. If that’s not true, this will be a bust. Nearest five feet is not adequate to develop a dive curve. I found discussion in another site where a guy doing the same thing I intend to do found it to be nearly neutrally buoyant when trolled. I think it dove to 5 feet 100 back. I’m counting on that being true. It is a 2.7 oz plastic device and is not as dense as a lead weight. I actually expect it’s drag to pull stuff higher, not deeper. We’ll see. If that manual is not correct about reading max depth to the nearest foot, I’m going to be upset
I suppose given its size it could be buoyant. Put it out 100 ft and see what it reads. If it does cause the diver to rise then it again isn't an accurate dive chart either. Weather or not the published are accurate......I would be incline to think they are.......it's what most ppl use and seem to get fish at the depth targeted using the charts.
Post back your findings
The fishhawk td arrived yesterday. I went out at lunch today and checked a couple data points at 2.5 mph in 53 feet of water on a local reservoir. On a side note, my new TR1 worked well and let me do this without messing with boat handling in 20mph winds. Line was Sunline 20lb which has a 12lb diameter. I checked the high end of the range first because that's where I thought the chart was wrong. 125 back was 38 feet with the fishhawk attached to the trutrip 40 and by sliding the probe to the diver, it measured 39 feet. On the western basin, I find that 45 back is often the 'sweet spot'. At 45 back, it was 20 feet using both methods. This is enough for me to say I now believe the published chart is correct. I'm not going to go through the motions of sampling any more data points. It's more time consuming than I expected. The fish hawk has a 'depth mode' that gives you temperatures every five feet plus the maximum depth down to the nearest foot. You have to change it to that mode for it to record max depth to the nearest foot. The next thing I'll look at is deep diving crankbaits with a snap weight. I'll only be able to tell where the weight is running. I really just want to figure out the setback to get a bandit and Reef Runner 800 running at 30 down for the times I fish the sandbar with a 2 or 3 oz snap weight.
Great to hear, also glad to hear that even though the td scales in at almost 3 oz......the have the size, shape, and buoyancy right to not appear to effect the dive curve in negative way. I would had guess between the weight and size it would had changed it. Wonder what it reads 125 back on it own......
