    Downscan with ai and carbon

    I recently upgraded from gen 3 and lss-2 to carbons and ai.the improvement in sonar and side scan are huge. My only problem is the downscan is not as detailed as before. I upgraded to the 20.0 software version and it helped but still not what it was. Ideas?

    So I have a gen3 9”&12” with the 3D transducer and box. Side scan is good down scan had never been good. I just don’t think there down scan is very good (lowrance in general at least there newer stuff) I love how the HDS works and the way points, point one,ect, that’s why I will stick with them.

    LSS2 is still good, even on carbon. And it has a frequency of 800 kHz on the downscan.

    Just upgraded to a live unit and updated all units to current software and I also don't have as clear a pic on my di on my trolling motor 3 in 1. When i select my 3d xducer on back down is great. Up front not so much is this what every is questioning? Didn't seem to have this on the bow with the carbon 12 before moving it and adding the live with current updates.

    Its been an ongoing issue with the AI trans that the DI is lacking. I have lives and the SI is pretty good but the DI is average.

    Could you add an lss-2 on a different channel?

    You could if you got a StructureScan HD module. Then the AI goes into channel 2 on the Live and the LSS2 goes into the module. Module connects by Ethernet to Live. Then you can select which source you want. However it will put the Live into Legacy mode and there are some features that won’t be available. Including Multisource.

    I agree...the sidescan and the sonar was a huge upgrade, but I really miss the downscan clarity. Anybody compared the carbon/ ai combo to the ss3d system?

    Are you running the newest .291 release. I believe intensity was increased on DI.
    Check the release notes.

    20.0 is the latest I have and I have been able to find. Is there a newer version for the carbons out?

    20 is the year it came out. There have been two updates released in 2020 for Carbon units 20.223 and 20.291. .291 supposedly has some enhancements to Downscan

    Yeah, my HDI transducer kicks all over the AI for DI.

    20.291 is the latest update I've found. Installed on all 3 carbons. It shows as the 20.0 software on my units. Not a big fan of fish reveal, but I run it on the front unit just for comparison. It is a good idea to run a split of 2 down scans, and add fish reveal to one of them. I'll try it.
