The On Time 00503 Digital Timer Replacement is a versatile LCD-display feeder controller designed to automate wildlife feeders across multiple brands. Whether you're managing a food plot rotation, supplementing natural forage during lean seasons, or running a consistent feeding schedule for hunting season, this universal timer handles the job without requiring you to swap out your existing feeder hardware. It operates on either 6 or 12 volt batteries, giving you flexibility to match whatever power system you already have in the field.
Setup is straightforward: program up to six separate feeding cycles per day, set each to run anywhere from 1 to 30 seconds, and let the adjustable motor speed dial fine-tune the amount of corn or protein that falls each time. The LCD display makes it easy to see your settings at a glance, and the universal compatibility means you don't have to guess whether it'll work with your feeder—this replacement timer is built to integrate with most standard feeders on the market.
For hunters and land managers who value consistency and reliability, a programmable timer removes the variable of manual feeding trips and keeps game on a predictable schedule. The 1-30 second run window gives you granular control: short bursts for supplement feeding or longer runs for heavier rations. Battery operation keeps it independent of AC power, so remote feeders are no problem.
