I upgraded to the HDS12 Gen 3, used units.
My previous setup at bow was Ultrex with HDS 5 gen 1 and I never had an issue. I purchased 2 HDS12 Gen 3's from a local bass angler that upgraded to the LIVE units. The HDS12 that I had installed at console works great, sonar works 100% of the time. The HDS12 that I had installed on bow will work with Ultrex US2 transducer and then it will stop scrolling but will intermediately work for a split second, depth will disappear but water temp still works. Sometimes I can restart HDS12 and it will fix the sonar scrolling but not everytime.
software is updated.
What could be the issue?
Thanks
