I have 2 nine foot Seeker rods that are made specifically for bunker spoons and Penn 4/0 reels loaded with wire line to get them down. I put a shot of leader at the end of the wire to attach the spoons. I attach the leader to the wire with an Albright knot.
http://www.fintalk.com/fishing-knots/albright.htmlI attach a swivel to the leader using an offshore knot.
http://www.marlinnut.com/knots/offshore.shtmlThe line goes out and the rods are put into side riggers so they are pointing off to the side of the boat.
I let the wire line out keeping in mind that
generally speaking for every ten feet of wire in the water your spoons will be down one foot. If you are trolling 30 feet of water you will have out about 300 feet of wire out. You have to keep a constant eye on your depth finder and adjust your line in the water accordingly. Remember the one foot down to ten feet of line in the water is only a guideline.
Your trolling speed is correct when you see a "whipping" action on the rods. They should have a steady pulsating motion. That pulsating motion is caused by the action of the bunker spoons. (I hope I explained that correctly.)
Now, just watch the rods as they will bend down pretty good when you have a hook-up.
That is how I troll bunker spoons.
