I’m totally spoiled to 640 core systems now, however ordered the Breach 320 because I was looking for a micro sized thermal mono to carry in my lumber pack while at work, hiking and hunting. Sort of a EDC thermal that’s so lite and small it doesn’t get left at home, however I have a thermal in a pinch if needed.
Overall, I pretty impressed with the Breach even for a 320 core system. The unit has rock solid construction, software and menu controls. The image clarity is top end 320 class plus the boson 320 core does seem to have better image contrast then the past Flir systems I’ve owned.
Overall, I find the Breach a great buy at its price point and performance is very good for a 1X 320 class viewer. I think it fits the tactical market/ home EDC and even hunters for close to mid range use. It’s weakness for hog/varmint hunters is the 1X lens for a full time hunting thermal mono I would perfer the Helion 384 with bigger lens and rechargeable battery pack.If Flir would offer the Breach 320 with 19mm lens that would really increase its field performance for hunters.
If the Breach fits your task I would go ahead and buy the 320 core system now. I may also upgrade to the 640 down the road but who knows when that will happen.
