The hot salmon setup right now is a flasher with a blinking light. You don’t have to buy a flasher with a light already installed. Instead, just buy the light. I use a $5 SquidPro Tail Light and put it between the flasher and leader. Works great!

Leader lengths will vary according to your lure, speed and currents. Lately I’ve been using a 32 inch leader with spoons and 30 inch leader with mini FAT Squids.

Stay tuned, in the coming days and weeks I have 15 Area 6 salmon charts I will be posting.
