The MK-1 Control Unit features a very accurate clock with a sleep feature that conserves battery power. A press of any button will wake the unit up! Six feeding times are available and the motor run time is programmable for each feeding. All settings operate forward and backwards. A progressive counter advances each time the unit feeds and a "smiley" face lets you know the solar panel is charging the battery. The press-to-test runs a complete system check and operates in conjunction with a motor delay safety feature adjustable from 0 to 99 seconds. There is a built-in lithium back up battery to hold settings when the feeder battery is disconnected. A five minute field repair is as simple as unplugging the electronic assembly and plugging in a new one. No soldering! All plastic used in Control Units is 100% Recycled Polycarbonate with UV inhibitors added (the same tough, flexible material that is used in safety glass).

The MK-1 Control Unit is supplied with a 6 volt rechargeable battery, 6 volt solar panel with stainless steel cooncable, small cone, cutting template, and mounting hardware.

Handmade at our facility in Texas from many US-sourced components.

1 Year (excluding batteries)

    Had one for 30 years pigs knocked over feeder and popped open bottom cover so I ordered new one but after being open to elements put a fresh battery old still works so spin cast feeders are the best feeders I have ever used and I highly recommend

    Been using these guys for over 20 years and for the most part have been served well. Get 4 years or more out them with little maintenence required other than batteries. Most have about 10 of them now.

    I’ve been using Spincast feeders for over 20 years and personally feel the MK-1 is the best on the market. I know I am running 11 currently and they are the simplest and most reliable units to operate.
