What Lowrance trolling motor transducer for video game fishing?

Do we know what transducer Jamie is using to get that image quality? https://bassu.tv/bass-fishing-video/video-game-fishing-lowrance-sonar-electronics-hartman

Or in other words what transducer do you recommend on the trolling motor if you have a Lowrance HDS Gen3 Touch in order to see your dropshot? HDI (with CHIRP)? Traditional Skimmer Transducer? Something else? I don't think he covered that in his seminar.
