Lowrance skimmer issue

[chowder]

6 year old Lowrance skimmer transducer: #1. A used rear station HDS unit stopped showing sonar information this spring spontaneously- hooked the transducer up to the dashboard HDS gen 2 display that had been previously Ethernet linked to the used rear station used HDS unit. Depth was displayed and bottom visible when in range but very little bait or fish detail. I swapped the used HDS rear station unit with the rear station unit from my other boat ( this one I had purchased new in 2019) . On the first trip using this unit the sonar information seemed normal . Yesterday I used this combo again and at first all was well but after I had gotten off the ‘shelf’ I was expecting the unit to show increased depth. It did not! I shut the unit off and turned back on. I was now on plane and initially it displayed no depth which I have experienced before so I thought nothing of it . I slowed down and began getting sonar information HOWEVER- despite being in range ( 250 fow / range at 300) the bottom was not displayed, changing range to 400 made no difference. Then I stopped getting any sonar information despite turning the unit on and off several times. I fished deep water with no sonar information despite turning. When I went in , I briefly had sonar information for a second once. When I got back into canal heading to the launch I suddenly had sonar information again in 12 to 6 feet until I shut off electronics at the docks. So- just replace the skimmer seems like the best move. Thoughts? Thanks
