I got my unit back in oct 18. With 93sv all was great. No ghost tree. Purchased new 122sv ultra and had to update for it to work. Boom...ghost tree.
Original unit settings TVG Low, noise reduction low, color amber, gain 65-75.
I turned ghost tree on low and it definitely takes some of the sharpness from the screen. Ghost tree and dead zone is still there.
On medium, ghost tree and dead spot fades more and targets begin getting distorted or out of focus. I changed focus to try to help but never could.
I gave up and didn’t even try high in high settings.
It is slightly better but no where near where it was 2 years ago. I ended day with it turned off and fishing through the ghost tree and dead spot.
Overall disappointed with results. I will mess with settings again to maybe find a happy medium. My hopes dimming though.
