Just got my sig 10k and very impressed with them huge upgrade on glass and can range things way better. Only issues im having is my bdx profile doesn't match to my kestrel it's always off .1 on wind ut something small to figure out and I noticed the sensors on binos get hot which can throw data off so connecting to kestrel is best. The binos update the dof so dont have to worry about that everytime on kestrel
