I hope this Question is not to dumb. If you would put on a stinger hook to this lure with the minnow tail is it still considered a two line set up?

1965 mustang 289 4bbl gas has .37 cent a gal and I still couldn’t hardly afford to drive it But I showed good responsibility and got to trade up to a 69 mach1 wish I still had it. If you haven’t heard that before.

Having flasher from the old lorrance green box to some of the newer ones I have seen allot of different problem related to battery but that does not sound familiar. Most of the time it a dimmer screen, flash slows, IR stops working, or if you have an older one with a alarm it will start going off. In the past if any my flash start to act up when I first put the transducer in the water a coating of ice cover the bottom this mess up the signal. Just pull it up and warm it with hand till the ice is gone. But in the pass I replace more transducers than box problems.
Good Luck

I most cases the flasher is faster in finding the fish. But your camera can teach you a lot of how the fish react to different baits and colors of lures which in my mind catch the fish especially when they are finicky.
