I know it’s not ideal but you could rail mount the 3n1, install that berley pro cover for it or even mount it on the rear handle. See how you like the transducer And if it’s worth it. Then you could Upgrade to a used 2019. Don’t think you’ll take the hit your expecting. I’ve got a PA on order. Figured might as well utilize the guardian while I’m at it. My brain believes the more money I spend the more fish I’ll catch. Times usually the thing that’s limited and trying to make the most out of it on the water. Not sure if you were aware of some of these mountings so I searched for some pictures.

here’s the ram mounted option for the total scan. Then you could have 2 transducer at your disposal.
