Hey guys not sure if this has been covered before but I took my boat out for the first time using a tzt12f and a b265lh. Ran the whole trip in auto mode but noticed the the high frequency has little to no noise and the low frequency has quite a bit of noise. I could pick up the bottom fine and didn’t test it’s limits was able to read the bottom at a 1000ft on both frequency’s. The low frequency was a bit hard to detect targets due to the noise in the picture but high frequency was fine. Just wondering if this is normal and if it’s recommended to use manual mode when using the low frequency.

Do you have photos? LF is more susceptible to turbulence than HF and many times mistaken for noise.
Sorry didn’t take any photos but will next time i will. Was just wondering if it was normal as I’m new to this setup. Just installed the scx20 to go with it so I’ll see if this improves the performance. The fish finder is really good at picking up the bottom though it did not lose bottom depth all day.
