Agree, let me clarify.......I meant to send the unit in for repair, you would be out 'both'.....Valid concern, however I just wanted to clarify some things! If the rangefinder stopped working, let's say the battery died, the binoculars would just work as regular binoculars. You wouldn't be out both. Even if you don't turn the ranging function on you can use them as just a normal set of binos.
