So after a different post by Troyboy I went out this weekend and tried some and actually caught a few nice crappie so thank you for that, but now I have more questions .
1- I want to say in the sonar tab the a beam width what does it do, more to the point it is better to run wide or narrow ?
2- chirp frequency’s is there a “best” range or should I be running the full spectrum?
