Here is a generalized Set up for fishing with a Flasher set up for Kokanee.
This is how you fish with out Down riggers.
What you need are; Flasher, Snubber, Rubber bands, Snap swivels or Duo locks, Cannon ball leads, and your Spinner or trailer gear.
You are going to want a assortment of weights for you cannon balls, 1/2oz, 3/4oz, 1oz, 1 1/2oz, 2oz, 2 1/2oz, 3oz, 3 1/2oz, 4oz, and very rarely 5oz, 5 1/2oz, and 6oz. The heavier the lean the deeper you fish. Remember though the more lead you have on the more line you want out to allow the angle of the drop to be able to make you lead at the depth you want it. The speed you are going will also affect how high your gear will plane. The faster you are going the higher it will rise.
You need a snubber when fishing this way. Alot of guys ask why use a snubber it is just like a big rubber band. Well the snubber takes a lot of the stress off of the fish, it will increase your catch ratio due to the fact that Kokanee have soft mouths and with out stress relief you will pull your hook out of the fish's mouth.
You want to tie a snap swivel, I use one with a duo lock snap on your leaders for 2 reasons. 1: it makes it easier to change your gear, and you do not lose any of the leader by cutting it off and retying it on, 2: the swivel will prevent the leader from getting all kinked up or twisted, the swivel also give the fish easier roll,(Kokanee cork screw through the water, twist and turn when you hook them trying to get loose).
Here is the end set up, I am sorry i was not able to take a picture of this in a straight line i had to loop it back to get the full image.
Now i want to note that you do not have to use a wedding ring for the spinner/Trailer gear. You can use all sorts of thing, Wedding ring, hoochies, apex, small spoons, K/T Spinner Bugz, K/T Bugz, and a assortment of other things.
The majority of baits that are used for kokanee are White shoe peg corn(plain), White shoe peg corn(dyed orange, red, green, purple), White Shoe peg corn (Dyed and scented, Paztke Kok fuel is one of my favorites) Berkeley Grubs, and some people use a small piece of night crawler.
When using the lead cannon balls i use a certain amount of pulls depending on the size of the lead i am using to make sure i get my gear in the zone. Some people use line counters instead of pulls. (1 pull = 2 feet of line out.) 1/2oz-17 pulls, 3/4oz 20 pulls, 1oz- 1 1/2oz- 25 pulls, 2oz-2 1/2oz-30 to 35 pulls, 3oz-3 1/2oz 40 to 45 pulls, 4oz or more in weight i go 45 to 50 pulls and no more inless you want your gear over 75-100 feet.
