The best reason to use Garmin is the Panoptix. If you are not interested in the Panoptix .I would suggest either a Humminbird Helix 5 or 7 G2 ice pack.
I run both the Garmin with Panoptix and a helix 7. The panoptix finds the fish faster than any method out there. With the possible exception of dynamite. Once the Garmin pinpoints them I use the Helix 7 to fish over them. If they move I break out the Garmin again and find them. The panoptix I am using is the PS 22. Obviously not as fancy and as expensive as the new Livescope Panoptix that Garmin brought out this year. But the PS22 is way good enough for me.
I agree, I have the Panoptix ice bundle and if you don’t necessarily want the Panoptix, it wouldn’t be worth it. I used the traditional flasher on it twice last year and after used only Down Vu (I do use Side Vu to locate fish). You can watch multiple lines and see fish come in from the sides.
