I currently have an XI5 motorguide tm with built in transducer and am looking to upgrade my front graph (lowrance chrip X5). Mainly fishing 8-30 ft depth in open water with the need for waypoints and also fish 2-15 ft water in fast water river current. What Garmin prooduct would you suggest for these applications? Also, what garmin units would be compatible with my built in transducer or would i be better off installing a new transducer if going with a garmin product? I believe the motorguide had a partnership with lowrance. I called motorquide and asked them which graph would work and was given the message that "any of them should work".
Also looking to replace the Lowrance Elite 7 HDI at the helm. I need a bigger screen that updates gps tracking faster. I would spend the money for 9" screen but nothing bigger than that.
Thank you for any suggestions
