Another update:
The new battery and charger came in. It turns out the guy I talked to at FLIR was wrong. He told me you could charge the pack either inside our outside the Scion. That is not the case. It turns out you can only charge it inside the Scion, but that is what I wanted.
I was able to compare the old PS32 to the new Scion OTM. First here is the difference in footprint:
You can see the Scion OTM on the left is considerably larger than the old PS32.
The first day I used them side by side, it was a rainy/cloudy day. Everything was cool and there was little temperature differences since there was no sun that day and no radiant heat to heat different surfaces at different rates. Everything was washed out in both units with little detail. I saw no animals so I can't compare that. I was able to look at a distant house. The Scion OTM clearly showed more detail there, but it is higher resolution, so that was expected. I found the screen to be much brighter on the scion. I have not attempted to make any changes to the setting yet. It seems to work better at longer distances. Today, it was partly cloudy with off-and-on rain. Again I saw not animals. There is a place where my neighbor had done some clearing and it created a cold spot at a couple hundred yards. With the old PS32, I could not really see it even when I looked for it. With the Scion, it popped right out. For closer objects, there was not anything obvious. The 60 hz frame rate is nice compared to the old 9 hz, but not really necessary for my applications
Again, I have not used the new unit on animals, but right now, I see no obvious advantages that justify the price difference for deer recovery or ensuring I'm not bouncing deer when I exit my stand. Of course the reason I went with the OTM was for my third application, off season surveys where I expect it to shine. There may be some advantage identifying antler configuration in the summer, time will tell, but the real advantage to me is the on-board recording capability. I have not used any of that yet.
As of now, if you are planning on using it for deer recovery, I'd suggest looking at the less expensive Scout line rather than the Scion line.
I hope to update this thread as I play with the unit and get more experience with it.
Thanks,
Jack
