If you figure anything out on it, please let me know, because I don't think it is anywhere near what it used to be. Gene I don't know of a way to turn (roll) back an update. I believe you would need Pulsar to do this. A list of the update changes that apply to different Pulsar devices can be found
here. It does list a contrast improvement on ID mode for the Trail XQ. I also saw this on another Pulsar post about the update:
Increase of temperature sensitivity in “Identification mode”
In units with XQ letter index firmware update increases temperature sensitivity in “Identification mode”. The feature provides better detection and identification of objects in conditions of low temperature differences (e.g. fog, precipitation, hot weather).
If you are having a hard time with getting a typical image quality or clarity, and humidity, etc isn't the issue, try the following: I have no idea why the following seems to work for people but it has for me as well. Supposedly the 3 different viewing (rock, forest, ID) modes simply make changes to Contrast and Brightness settings. However, on more than one occasion, I couldn't get my Helion image to look correct. I then reset the scope back to factory defaults, and switched the mode back to ID mode from Forest or whatever the default was, and then tweaked my contrast and brightness to where I normally have it set to and it worked. If you do this, before you reset the device, write down your X,Y coordinates or you may have to sight your gun in again.
I updated the Helion with the last update and didn't even check the image. However, one of the main things they changed was how their devices connect via Wifi. I am assuming this is due to the issues they had holding a connection to Apple devices. After completing the update, I launched StreamVision and it held a connection to my iPhone for an hour. I can't remember if it ever was able to do that. I purchased a cheap Amazon Fire tablet in the past as I had given up on StreamVision/iPhone integration. In my limited testing, the connection to my Apple device was more stable.
After reading this thread, I went to the Facebook site known as the Pulsar Night Vision and Thermal Hunting Group. This group has around 10K Pulsar users. Typically, if there is a major issue with an update, lots of people start to comment on this site and no new threads at this time. If I hear anything different, I will make sure to respond back to this thread.
