I apologize on the PIP incorrect value for the OTM. I read over the information on their website and didn't see it or a detection rating. I updated the chart as I also found their detection information after a lot of digging. With detection, it depends on what they are using for size for detection, so it isn't always an apples-apples comparison.
I know Flir says the battery is 4.5 hours but they never seem to live up to their ratings for any company. They must test them in 80 degree weather. Pulsar indicated 10 hrs on the Helion when they first came out and I can barely get 5 if I am lucky in colder temps. Most places list 8 hrs for Pulsar but that is still a stretch in my opinion. However, I updated the chart to reflect what Flir states.
Bering Optics has a 640x480 scanner called the Phenom. I have one that I am testing right now. I will talk more about this scanner in the future. As far as the Hogster is concerned, I can ask Bering Optics this question at Shot Show. I kind of doubt it, but you never know. This scope was designed to appeal to a very large audience with a scope/scanner combo at a reasonable price. When you go 640x480, lots of times it prices many people out of the market.
I can tell you that I have had the Hogster 35mm in the field with my Pulsar Helion XP38 which is a 640x480 and it isn't very far off from an image standpoint, and in my opinion it has a much better image and detection in comparison to the older Flir core used in the Flir Scout III 640. What I am getting at is many people are stuck on something has to be a 640 res whether it really is an improvement or not.
It does appear the Scion is 640x512 res. Flir has it on in their product drop-down page listed as 640x480, so I changed this as well on the chart. Thanks for the clarifications.
