I expect this is a rare occurrence but here is a tip if it happens to you. As the temperature drops, the zoom knob on the left side of the scopes body becomes sluggish. When it gets below freezing, it stops working. I have been unable to find an alternative way to adjust magnification. Last night I placed a hand warmer under the body of the scope - problem solved. At least until all the heat was sucked out of the hand warmer. Just a tip for others that may have run into this problem.

Hmm. I haven't ran into this problem in 5 years of ownership. Are you in a climate that goes subzero? If you have the phone app, you can always zoom with the app or the track wheel if you have one.

This problem is getting worse. The temperature at which the wheel becomes unreliable is increasing. It was mid-50s last week and I could not consistently perform magnification changes. Probably why ATN eliminated the wheel on the new models. I believe it involves wear and tolerance of the encoder wheel. Temperature changes affect the tolerances.
revcharliep, thanks for the tip about the track wheel. using a phone app wouldn't be acceptable for quick zoom changes while engaging hogs. I keep hogs off 3 ranches and I cannot afford the time to send the unit in for repairs.
A Step zoom function would be good but the zoom level is insufficient on the new LT models for the resolution they are capable of. E.g., the 640 resolution is only 2-6x. I have that resolution in a THoR and I'm using 15X or higher to shoot coyotes out to 400 yards.

Oops, doesn't look like ATN offers the trackwheel anymore.

G'day,
I've noticed that the zoom wheel turns but the magnification increases more slowly quickly in colder weather - close to zero C on my 4K Pro 3-14. If I turn the wheel too quickly magnification doesn't increase at all. I must turn the wheel very slowly in colder weather. Fortunately, my shooting has improved enough so that I am shooting using lower magnification with success.
