I would assume the Seek is better than the FLIR One I have, but be sure you have a realistic expectation. You are not going to get the performance out of a $300 clip-on phone camera that you'll get with a $3k Thermal Monocular. You'll see a hot something at some distances, but to think you're going to "observe wildlife" out at any distance isn't going to happen.
I do wish you luck with it.
