Looking to finally pull the trigger on Livescope but I have never had Garmin units before. I run Lowrance and Humminbird currently so don’t know my Garmin models no am a bit overwhelmed. I feel like Garmin has more models than the others and I can’t make heads or tails of their website. Can someone tell me what unit I should get if I am ONLY going to run livescope on it? I’ll keep using my others for mapping, down scan and side scan.
