The FL-8se® Genz PackYears in the making, this classic design has been improved even more by ice fishing legend Dave Genz. Dave has made his “Blue Box" nearly indestructible so it will last for years of hard use. Genz redesigned the battery storage compartment and added a universal transducer holder system.
The Blue Box can also accept the full line of Vexilar accessories like a Battery Status Indictor, Vexilar Flex Light™ or even a Dual Beam Ice-Ducer transducer. The Blue Box fits on top of a five gallon bucket for easy access and handling while fishing. Available with the Vexilar FL-18 or FL-8se. Each Genz Pack Combo comes with a 12 volt, 7 amp-hour battery with charger and an Ice-Ducer transducer.
The Genz Pack comes completely assembled and ready to fish with. It also includes an instructional video.
This classic FL-8se flasher is truly legendary. The world’s most popular three-color sonar flasher, the FL-8se is still one of the best all-around flasher/sonar designs. The hallmark three-color display shows weak targets in green, medium strength targets in orange and strong bottom targets in red. 525 segments of resolution, super bright LEDs and 10 interference rejection settings make the FL-8se a great year-round flasher/fish finder.

The Gain TrickWhile fishing deep water suspending crappies I generally turn up the gain on my FL-8se to see if anybody's home or near home (the hole I'm fishing). I believe a lot of anglers tend to move to another hole to quickly. Just because you can see your tiny ice jig and don't see fish on the screen, doesn't mean there isn't fish near by. This is when I turn up the gain to see what might be on the sides of the cone angle. You'll be surprised of all the fish you may have left behind. Once you see those suspended fish off to the side, start pounding that jig about two feet above the mark and watch them come in!

No matter what unit you are using is to make sure the bottom of your transducer is always clear of ice and is in a position so it is not reading through the ice. Particularly the inner walls of your hole. So many times our Perch Patrol clients tell us that they cannot see their lures and their gain is cranked way up. I always turn their gain way down and remove the transducer from the hole and clean off the film of ice that has formed. This cures the problem 80 percent of the time. If there are still problems, I start focusing on the position of the transducer in the hole. What happens is as the ice gets thick, 24 to 36 inches, if the transducer does not get a direct shot to the lake bottom it tends to read through the ice near the bottom of the hole.
A lot people will try and correct this by lengthening the cord to the transducer so it sits below the ice. I don't like this as fish tend to get caught in the cord more often. I find a spot in the hole where the Vexilar receives that clear shot to the bottom and I weight the cord down with the Vexilar unit itself so the transducer and float will stay in one spot. This is also the perfect scenario for using the Genz pack with the eye bolt. Hopefully this will help you see your lures better at the lowest gain possible to reduce any interference issues.
