The Game Feeder II gives you more flexibility and options than the basic Game Feeder I. The time is set the same as the Game Feeder I, but for your second feeding you have a choice of 8, 9, 10, 11, 14, 15 or 16 hours after the set time. This flexibility with your second feeding allows you to set the feeder in either the morning using 8, 9, 10 or 11 hours for second feeding in the afternoon, or set the timer in the afternoon and use 14, 15,or 16 hours for your second feeding in the morning. The two-battery power supply or the optional solar panel provides more energy to operate the unit than the single battery Game Feeder I. All adjustments and settings are easily made using the one external switch. This allows you to test the unit with a 5 second delay for safety and adjust the spin time of the motor without opening the timer. One year warranty.
