I gave my daughter a Tesoro Silver Sabre detector many years ago, and she traded it back to me a couple of days ago for a newer detector that works - at my request. I'm trying to keep her interested in the hobby, but she's having a ball with her new magnet fishing craze. Anyway, the Silver Sabre has an open battery compartment, and is missing the battery module. I don't even remember what type of batteries it requires. I'm hoping someone will remember what batteries it requires, and what plastic module. Any help with figuring this out will be much appreciated. Maybe there's a site online that has the manual?
