Bitter Sweet!

I love the ATN 4K Pro 5x20, but hate the app so far. I have been trying to create profiles many ...many times without success due to when I apply the changes working within the obsidian 4 app; the scope locks up and the app loses WiFi connection. So....I tried to do everything from the scope and it has worked fine except there isn’t anyway to rename the profiles within the software of the scope. The only way to do is from within the obsidian 4 app. On a good note....I have been able to edit settings in the app and it successfully changed within the scope. I have successfully downloaded some pics and a short video, but it has been a very hit and miss due to lock ups in the obsidian app and a slow download time. Please fix these issues and you will have a lot of happy ATN customers!!

Decent when it works

I’ve been using ATN optics for over 15 years and have gone through the many growing pains of ATN with their Xsight and Thor products. This app is useful after you manage to get it to connect via WiFi to your phone. For some reason it never connects the 1st few times, but always manages to connect after several attempts. It doesn’t have the greatest layout, but does make configuring an ATN THOR 4 or Xsight 4K easier than from the optic itself. There is 2 seconds of lag during live view from my Thor 4 / iPhone 8 Plus which is very disappointing as this is nearly useless for hog hunting. I appreciate ATN trying to provide cutting edge features to their customers, but this has given them a reputation of releasing beta quality products and software that can be frustrating to use when they don’t work as advertised.

Sub par at best

So far the optic and app have both disappointed. Optic was mounted to a firearm with the INCLUDED rings. Rifle fell off of vehicle seat to the floorboard(less than a foot) and the optic broke in half. It didn’t break the glass or crack it, it broke the tube COMPLETELY IN HALF. For the money you pay for this optic it should be made with better materials and not pop metal. Sent the optic back only to be told once it reached the technicians that it wouldn’t be seen by them to diagnose for 15-30 days. Then who knows when I get it back. Guess hunting this season is out.....
