Quit working in only a year? Do you know what happen? Are you sending it back to get fixed? So I will ask How has your performance with non braked rifles been ?Good timing for this post. I,m about to start testing a few braked rifles with my Labradar for the first time. I have been using the Labradar with unbraked rifles for a year or so and the port for connecting the remote battery has stopped working, so I use rechargeable AA batteries and they work fine. I just keep a dozen or so freshly charged AA batteries in the Labradar bag.
