Chirp comments from users?
The only time it really makes a large difference if you are specifically looking for smaller bait fish and what not. I Still honestly prefer normal 200khz normal sonar or CHIRP Medium alongside 455 down and side scan. I have been in numerous of different people's boats for my lessons and gotten to experience tons of different setups and it is still my preferred way to go and normally theirs as well once I show them the differences.
TLR- Chirp is an improvement but not HUGE
