I'm looking to upgrade my Humminbird 998. I'm having a hard time deciding if i want to go with the Garmin GT56 transducer with Ultra 102 screen, or stay with Humminbird and go with a Helix 10. I've heard the garmin gt56 is better than Hbird for side imaging and all that jazz.... What do you all say? Any experience or screenshots anyone could share? Much appreciated.... cheers.
