Buy a probe is definately a big help. You want to keep your lure speed somewhere between 1.8 and 2.5 mph. My experience is that for Kings you want to be in 40 - 50 degree water. Use your chart recorder and look for fish marks and bait balls. Fish can be in depths near bait ball depth. Use spin doctors, e-chip flashers, spoons, twinkies with cut bait, and flies. Use copper, lead core, wire, dipseys, etc, etc, etc. All these things work and I use them all. Practice, practice, practice. The big thing is to get out there and see what works. Some times the planers hit, some times the riggers hit, sometime copper down the shoot (straight out the back) hits. Try it all, it is a great time! That's why they call it fishin and not catchin! Good Luck!!!
