Hello,

Please forgive me in advance as I know there have been similar questions asked but I have not found a definitive answer or one that does not seem convoluted. I have posted this same post on BBC as well.

I currently have two gen1 units with an lss-1 for ss and a shoot thru for 2d. They are both networked and have nmea2000 for sonichub, gps puck and motor readings.

I have purchased two HDSLive 12's and am looking to install. I could replace the lss1 with the AI 3-in-1, get the 7pin to 9pin adaptor for the 2d and call it good, i assume?

I have read several reviews stating that some get better reading with the lss1 and some say the 3-1 is not much of an upgrade.

Before I remove the flushmounted lss1 from my rear setback of my Rangerz520 and fill holes (which im not excited to do) and then redrill to flush mount the new 3-in-1, could I just use the lss1 plugged directly into my Live unit at the console and see what type of images i get? Will there be any software updates i need to do or any difficulty in setting up the lss1 in the sonar installation screen, or any legacy mode issues?

Some have said an impedence adaptor is necessary when plugging and lss1 directly into a carbon or live unit but i'm not sure what this is and after an exhaustive search can not find this part online anywhere.

Any help would be greatly appreciated before I start this process.

I would ask Lowrance.

Old post but in case you haven’t got an answer yet, the LSS1 will plug directly into a Live and provide Side and Downscan. No adapters or anything else needed. AI 2in1 would be a better choice than 3in1 since you already have a 2D transducer. But to answer whether AI is better than LSS1, yes in everything. Some have said the LSS1 had a better Downscan but I’m pretty sure a casual user would see no difference and the extended range of AI makes it the clear winner IMO
