With a little research I found out I needed to upgrade the transducer and make a few adjustments in the settings according to the lake you're fishing. Once you open the new unit Humminbird will not give you a full refund or exchange on the transducer. Your best bet is to keep the old transducer in case of emergency.
Thanks, I was afraid that was the case. I'll keep tinkering with it just a little bit longer before I spend the $200 but I'm afraid ill have to spend it eventually.
