I bought the same Caldwell as the OP back in January. Been very happy with it. My one observation is that pellets must be shot very low across the sensors in order to register. I disconnect the battery when I’m done using it and store it separately. In the humid coastal environment where I live the salt air quickly corrodes exposed electrical contacts.
I see lot of guys cant get apple to work on there's. Maybe explain your setup or how to ..Good to see yours did.
