I have not owned an ATN myself, but one of my regular coon hunting buddies bought one (I forget which model, but recall retail was ~$2700). It worked well for a few months, but then would not power up any longer. He’s 16 months into his warranty repair/replacement cycle, and they haven’t given him an answer as to when to expect resolution. So he had a product for ~3-5 months, it failed, and now it has been over a year which he hasn’t had it because they’re taking too long to fix it.
That was enough to turn me off of their “attractive prices” when I’m looking for my next one.
