Says 250-800 yards
I know it is better than my maxx, I can verify that
I have hay bales 80-100 from the back of my barn, and my Maxx would NOT play on ground by bales.
With the new mighty atom, it DOES play, stop, every command I press, it does want I want it to, so it's a upgrade in my book
I put it out of sight, in front of hay, so I could see it and it was obstructed, and it played, so I am pleased
I do not hunt with my caller over 100yrds so I did my own test to what I use, everybody has there own preference.
