Re: Trolling speed and depth
Trolling is something that I love to do, the reason is you can play with the baits in so many ways to get them to do what you want. Umbrella rigs are awesome for attracting fish but the weight of the rig kills the fight. Here are a few tips for making the most of an umbrella rig.
Do not buy a pre-rigged umbrella. You can rig and re-rig an umbrella for what a pre rigged one cost. And you can play with all sorts of things on the rig. I usually run them with alternating chartreuse and white lures around the rig. Sometimes I replace an umbrella bait with a de-hooked rattle trap or other noisy bait, also a dead bait or two can be substituted for scent. You can play with the weight, if the weather is going to be a little rough adding 2 ounces onto one leg will keep the rig stable, sometimes they spin which does bad things to you stainless cable.
Speaking of stainless cable it comes on your downrigger. These are really expensive, but cannon has a minie troll which you can get for $100. I wouldn't waste money on the accessory pack you will probably not need the weight. The really cool thing about these is that you can double or even triple stack umbrellas on them which would certainly break a pole. For my trailing bait I use a little trick, at most pharmacys you can get rubber bands for braces. These work great for pressure releases on the back of the rig, just make sure you keep the pole with the lure high compared to the rigger so it will not tangle in the line. This gets two baits in the water with the umbrellas, now you need to get a few more in to cover the water column. Big Jonas has a deeper diver that allows you to adjust the direction (left to right) and the depth of the lure. Someone else may have one too I dont know. These work great for setting a water column line that can cover 40 to 50 feet of dept with only 4 lines. If you dont want to go to all this trouble there is a bottom bouncing modification that works with almost any lure. Tie a three way swivel on the end of your line, measure out the leader and connect it to the next ring on the swivel and then use a weight on third leg of the swivel with the appropriate amount of line to reach your depth with the lure. The important thing here is the weight, use a cylinder drop shot, these dont seem to get snagged as easily. Also please dont use lead weights, it may cost more but other materials are just as effective and dont poison the environment. As for speed with umbrella's 2 to 2.5. For other baits I don't know.
