Our Platinum Plus timer is very user friendly and features up to 8 feed settings. There are only four buttons- Menu, Hour, Minute, and Test. These timers are designed to mount flush inside the door of our controller boxes, but can be used for any feeder 6v or 12v. Field tested, these are proven to last. Many customers have verified 10 plus years in the field without issue. There are only four wires, two to battery (red positive / black negative) and two to the motor (yellow positive / green negative). After years of trial and error, Platinum Plus is the best timer Magnum has made, therefore; it is the only timer we currently offer.
