Hi guys,
Im wondering your take on “Precision Trolling” book and what you all think of it? Is it worth it? If so, what type of lures is there that it shows the depth curves for? Also does it show a number of different speeds or just a couple?
All the informtion would be appreciated as that Im looking on buying it!
Personally, i like it. it has about 120 lures of which i use about 8 though. its a good resource to have but not NEEDED. I would buy it again if i lost it. If you are pulling core its a bit less needed. Guess Im just retaining my learnings from it and ledcore pulling depths. it is a great base to start from. It gives 2 line types 10-4 fire amd 10# mone curves. Not speeds for pulling. From exp im guessing it was compiled at about 1.8-2 mph. If you are starting cranks i WOULD get it. and leadcore too. knowing that core will add roughly 5′ of dive assistance at 2mph per color out. that is 5’per color in addition to the lures dive at distance back. Since starting Superior fishing I have purchased the Big Water Edition too. It has more info on snap weights and lead core tactics… maybe take a picture of that at the store??? if u dont need the whole book. 
That sounds very helpful. My next question is where Im most confused. It is if Im pulling leadcore and I have a 15′ flourocarbon leader then my lure. If the leadcore pulls at 5′ approx. then the lure say a shad rap pulles at around 4′ to 9′, then how much would my depth be then….? Im pulling around 2 mph.
do you live close to a gander mountain or cabelas? you can look at there store copy. 
You are thinking a bit too hard on this. Using the mono curve figure the total length of the line out as the depth it will achieve then factor the added depth the lead you have out will get you. that sould be where your lure is.
(5′ per color, each color is 30′ and NO 27# core is not heavier than 18# the outer line is just thicker meaning more water resistance)
I use the mono curve since leadcore is a larger dia.
Its not a perfect system, there are and will always be variables that you will have to realize and make adjustments. Its something you just have to experiment with. If you walk through it like i explained above considering 2mph you should be in the zone.
Remember when you are marking fish they are generally ranging from on the bottom to 2 maybe 3 feet off the bottom… so the zone is somewhat large.
If you really question the numbers find a consistant sand flat, Say up near Malmo on Mille Lacs and put the rig out and take notes when the lure starts thumping bottom. speed, feet back, lure type and size, and water depth.
Remember it is a non-linear formula. a “curve” not a diagonal line. Buy the book, trust me. Oh yeah, keep it in a zip lock or the pages will stick when it gets wet –like a 13 year olds playboy. even the “pro-edition with the Plasticish pages stick.
Naz,
Just let out the 15′ floro leader and hold your rod tip
at the waters surface. Assuming the water is clear, now
you can see how deep your lure is running off the end of
the leadcore.
I personally believe every good troller has one of these books. It shortens the learning curve and for $35.00 it’s a huge asset. 
would not troll without one – period.
As was mentioned, the best investment to increase your success at trolling – whether contour or open water. Mark the fish, look up the curve and place your bait above and sharpen up your knive…
Good luck with your decision!

I really appreciate the help from you all!
One last question. I dont want to sound like an idiot but here goes.
The depth chart shows “X” feet down and “X” feel out….if you want to get deeper would you just double the chart?
No, not necessarily. All lures have a max dive point. They will only go so deep at certain speeds no matter how much line you let out. As a matter of fact, at a certain point it can be detrimental to the lure diving.
Get the book, it has a lot of good reading in the front about trolling.
Thats the answer I needed. Ill get it. Thanks again guys!
I’ll definetly let you all know how it goes.
Just a side note to this that many OFTEN over look. It is one of those fine details that I believe puts more fish in my boat. If you run line counter reels I would check them vs. actual # of feet out. I have 100′ taped out on my driveway and I verify my line counter reels against the actual. It depends on how much line you have on the reel, but what you find may surprise you and you could be way off from where you think you are trolling. I would suggest making sure your reel is almost full of line to get your line counters fairly accurate. I then write it down for reference for reach rod..
Example: Rod A 105’ of line = 100’ of actual. Etc. I’m a lil anal when it comes to this. 
I would not troll with out the book either.
Just my $.02
That’s a great point Lip Ripper. I put mine through the test a couple summers ago, and couldn’t believe how far off they are. The more line out, the further off it gets as the spool gets smaller… I have a question though… I always use a 30′ mono leader on my lead rigs. What I do is use the book to see how far a lure dives with 30′ of mono out, then add 5′ of depth for every color out. Is this not correct?
Kooty is correct.
Because more line is let out, it creates “lift” against the water and can raise the lure.
Good point Lip. I have one line counter that when I cranked up 450 feet of line, it said I had over 600 on the line counter!
Also, 20lb “original” Spiderwire goes a LOT deeper than 20lb Spiderwire Stealth! Like 10% deeper!!!! So, line types do vary quite a bit.

How does that happen? Are the diamaters different?

That is correct.
