Hey AF Dude,
I don't think it's so much that is top secret, but that there are so many variables, it makes it difficult to give simple answers. Most lures have a known trolling depth based on 10# test line, 100 feet of line out, and speeds between 1 and 3 mph. Generally speaking, most lures will run deeper when trolled then what is shown on the package. That rating is for cast and retrieve fishing, with a few exceptions like the Rapala Trolls-To series. If you want to get exact answers, you may want to look into getting a book called Precision Trolling or request a pamphlet from the lure maker about trolling depths. I am pretty certain that Rapala has a pamphlet you can get that will help you figure out lure depth, based on trolling speed, line diameter, etc. Changes to any of those factors will change the depth of the lure. However, most of the pamphlets are based on flat line trolling and not downrigger trolling.
A good rule of thumb when you are starting out with downriggers is to use floating or shallow running baits (i.e. 0 - 3 ft) so they are at
about the same level as your downrigger ball. This should help you control the depth of your bait. If you have two downriggers you should always, in my opinion, use a slight variation between the two, until you figure out exactly what the fish want. I like to start with one rigger within 2 ft of the depth that I am marking fish and the other one 5 ft above that. I also like to vary the lure style and color between the two, as well as the amount of line I let out before hooking to the ball. I usually start with one 50 - 75 ft behind the boat and the other 100 - 150 ft behind the boat.
Some lures that work well for me are as follows.
For trout you can try original floating Rapalas, needlefish, krokodiles, or tube jigs. As for color, it depends on where you are fishing. Matching the natural forage is always a good place to start. For wipers try shadraps, x-raps, pointer minnows, lip-less rattling crankbaits and shad is always a good color to start with. If that doesn't work try something with a bit of flash or brightness. Kokanee are targeted with a flasher or dodger followed up by a wedding ring or a squid. Hope this helps get you started. Fishing with downriggers is a lot of fun and can be very productive once you figure it out. Just don't get frustrated and give up on it. Feel free to pm me if you have other questions, I might even have an answer for you.
12inchlunker, don't mean to hijack your thread. Have you checked out
www.overstockbait.com yet? They have a small discount, but occasionally have some decent sales. Also, watch for Cabela's 25 - 50% off sale on Rapala. It generally happens once or twice a year.
