I too own an FLX-28 vexilar that I absolutely love. The thing performs like a champ. The only upgrade that I might do is put a lithium-ion battery and replace the heavy lead-acid battery. I picked up one from Dakota lithium and tested it on the vex and the 7 amp hr battery lasted beyond 8 hours at room temp, so I guess maybe I could get 5 or 6 hours at colder temps. But it makes the unit so much lighter to carry. I have owned the Humminbird ice 35 and the Marcum LX-7 both. The Humminbird did okay. The Marcum bit the dust after a year past the warranty. Somehow it got water inside the unit near the screen and it was toast. I should have originally went with the trusted name in electronics the first time. You live and you learn by making mistakes. My two cents....
