Looking for opinions on thermal scopes....not clip-ons....in the 5 thousand dollar range. This is my first thermal scope. I've been watching you tube videos until I'm cross-eyed....Pulsar Thermion..Iray Rico...AGM...Bering...not sure what to do here.....do I save up for a Thermion Duo....does the AMOLED vs OLED display make that much of a difference?....I'll be using it in northern Oklahoma in open terrain. I'm not a serious hunter I mainly want it for pest control in the pasture...prefer to have LRF but not a deal breaker to not have it...I do not own a scanner and since I'm not using the scope for hunting do I need one?. Not sure what to do here. This is a pile of money to me. Thank you for any help or advice
