I use buzz bombs when I cant get silvers to the fly. I try to jig the fish up to the surface. If I am reading fish on my graph down around 40 feet or so, I start there until I feel a tap, then I reel up like crazy. The fish will follow them up! once I can see the bomb, I start jigging, slowly working it to the surface. The trick is to NOT hook a fish down deep. we have made them chase the bomb out of the water! Its a kick. I use them a lot out of Neah bay and sekiu. Often catching too many to count.
