Re: trolling setup
I troll for trout in No. Calif. lakes using a Penn 209 reel, a garden variety 6' or 7' pole, 12 lb test leaded line. At the end of my leaded line I attach 6' of 6 lb. test mono line with a Luhr-Jensen Needlefish Pearl Bikini (#1 size). For every color of leaded line out (10 yards), you are down about 6' or so. A fish finder is a must...Bob
This is good info, but I found I get about 5-feet-per-color out of 18# pound test leadcore. It makes sense that 12# lead may run deeper being thinner. I actually didn't know it was available smaller than 18# test, so thank you for making me look that up. When I did, I found
this article which I thought was useful and had some good tips. My leadcore has been soaked in the depths enough that my colors are not real obvious until they get wet again, but I am spooled on a line counter reel, so it's less important.
bobo1's suggestion is a good one. The original poster was inquiring about trolling down to about 30 feet. Leadcore is a good tool for that if you have the space to get it set up and run it optimized. I think that leadcore really shines 15' down to 25- or 30'. It works OK 30- 40', but (at least for me) you lose feel and sensitivity once you have 200 feet of weighted line in the water- it absorbs fish action and I think I miss strikes that deep...
Now I'm on a roll.... sorry for the soon-to-be long post. Not really
In vermont, many of our local lakes are smaller with a lot of shoreline points and breaks. Turning on these lakes is tough with a lot of lead out especially if the leadcore is on the inside of the turn because it sinks when it slows down. Lead is better on larger, more open lakes that give more room to turn around.
The other thing about lead is that you are far behind the boat with the lure. By very nature of trying to get to the mid depths (12-25 feet) you wind up 100, sometimes 175 feet behind the boat. I think being way off the boat improves strike potential a lot.
After leadcore, if you don't want to add downriggers (which I have run at 2 to 5 feet to keep light Sutton's from jumping to the surface from line friction in wave action), I have found very small BigJon Diver Discs to be useful. They can run you even 30 feet of the side of the boat and be 15 feet down depending on the lure and speed. I have caught salmon, rainbow, and walleye using these with a leader the length of the rod. I have some Dipsey Divers, but (except for Walleye) I seem to get better results from the
Big Jons. Your mileage may vary.
I also use several medium spinning rods: composite, 'glass, or cheaper graphite. Some might say these rods are "soft"
, but I spool them with 20# braided line (6# test diameter) and a rod-length leader of mono which gives an unbelievable amount of feel and does not stretch: leaves the rod to deliver all the fight. The thin braided line runs a little deeper than mono, and puts up with snags and the pull of Diver Discs better than mono. An 11 or 13 Shadrap will run to 16' on this, and a (more appropriate for your trout) Rapala "Original Floating" 9 silver/black can go 4-5 feet down on braid.
So that's the sum of my mid-depth methods. rolmops and bobo1 might have better advice on presentation and baits. Unless you are fishing in New England, then I might be able to suggest a few things
I don't know everything; just trying to help and love learning and sharing both.
Good luck!
