We use shallow bandits in the spring on our downriggers. We set the riggers to cycle up and down to cover all the water column and make quick depth adjustments.
We have found the eyes move up and down more in the spring than any other time, as the water temps are not as stable. We can be catching at 25 ft and the sun pop out and the bite can go high to 10 ft in a matter of 30 minutes, or turn around and drop back down again. The bandits tend to catch the bigger fish.

Normally, in the summer the fish moving up means they are more actively feeding, this does not seem as strong in the Spring. The temp changes help congregate the bait and the eyes follow and feed whatever the depth.

BTW - I am aware that downriggers aren't used much in the Western Basin, but we depend on them every time of year to fine tune our program. They are fast and efficient tools to fine tune the best depths. In the spring we pull shallow bandits and large Colorado harnesses pulled slow on the riggers to start every trip.
