This seems to have started after the most recent software update. My transducer is mounted on the 2nd step down on pad. It's always "lost signal" at high speeds, which is ok. I run two units at my console. The other unit is an 1198 which has a thru hull for high speed depth reading. The Helix is used exclusively for down imaging only.
It takes 10 - 15 seconds to catch back up and start reading once I come off pad. Seems to be a recent thing when I updated to most recent software.
Anyone else seeing this?
