Villagenut Posted August 10, 2020 Posted August 10, 2020 I recently purchased a 2016 boat that has two hds 9 gen 3's linked (console and bow). I don't fully understand everything but it appears that they were set up with the y splitter and for a "thru the hull" transducer for 2d sonar and then a side scan/down scan transducer on the bottom of the jack plate. The reason i assume this is that i get 2d sonar while on plane but not downscan/side scan. 1)So i guess my first question is "based on what i have described, is my assumption correct that there are two transducers"? 2)My second question involves a possible upgrade. If i were to upgrade to an hds live, would the new unit use the same transducers or would i need to upgrade them in order to take advantage of the better screen and newer technology of the hds live's. Not interested in the lowrance live as i plan to go with garmin for that. Just looking of better resolution for down scan side scan. I hope all this makes sense. Thanks! Quote
