Get some halibut snaps and hook a downrigger release to them. Snap it on your wire 10 feet above your other release. Stack the rod closest to the stern on second so they don't cross and tangle when a fish hits.

I use divers all the time, but only in fairly shallow water like B10, Willapa, Grays Harbor, etc., and mostly so I can get down quick and avoid flatlining in those typically crowded areas. I also use them in the Straits when I am fishing a lot of people for a lot of fish, like for the 4 fish humpy limit - otherwise when fishing is hot you spend too much time cranking up wire. I don't ever use a deep six, however, I use a locally built diver that self-sets when a fish hits but doesn't stay hooked. Again, saves time out of the water. The more time in the water the more fish
