Not many video's from the field to look at. Depends on what you want to spend. I would want to compare it to something else or hear comparisons from some that have. Has a 1450 detection range but not sure what recognition range is. If you can afford a 640 scope I would definitely go that route. Make a list of everything you want in a scope, FOV, LRF, recording ability, PIP, battery life and easy of changing it in the field, ranges you will hunt at, price you can spend, warranty, manufacturers stand behind product record, etc. Then start checking the boxes as you compare and this should get you close to where you want to go.
