Has anyone used one of these with the chirp transducer ( Airmar TM150M ) which provides chirp for traditional sonar and down view? If so , what is your opinion ? ( image quality…target separation etc. )I will be replacing my Humminbird 957 bow unit. I have two of these units on my offshore boat. Its fantastic and the definition and speed of the chirp is better than traditional sonar. May not make as much difference in shallower freshwater but the response time in deeper depths for me is great 150-200. You will really enjoy the touch screen and the chartplotter. Best mapping around IMO.
