Question: Will this unit fit inside a varmit guard?
Document: I ordered this feeder to replace an older dusk/dawn unit. Installation was easy and it is completely self-contained so no wires to be pulled loose by the local squirrel population. Note that it requires a special battery, a standard 6 volt spring top battery will not fit in the battery compartment without modifications, trust me it is easier to buy the right battery! The manufacturer calls for a DE645DC (their #) which is a tab top battery that must be narrower than a lantern battery. The timer programming is straightforward and gives many feeding options.
I put this unit on a feeder in August of last year and had it feeding 4 times a day throughout the whole season. I charged the battery before putting it in the field and I never had to touch it again the whole season. It is still in the field even without me refilling the feeder as often as I should and is still spinning every time I check it. The test function works well and the spinner plate sends the corn flying so you have to get out of the way.I used some heavy gauge 1 x 1 inch fencing to make a varmint cage for it since it's unique shape doesn't fit standard cages.
This is my third SunSlinger; very dependable in the worst conditions. My oldest one is 4 years old and only replaced the rechargable battery and AA battery once. This spinner will throw corn or small protein 10-15 feet. In fact I have my spinners set for 1 sec. once a day during the off season months just to keep the 55 gallon feeder running for two months straight in Texas. The only problem with this spinner is that you will need to create your own varmit cage. Nothing on the market works or flat just doesn't fit over the long spinner.
I'm leaving this review as I order another unit for another feeder for the 2013 season.
I own 6 of these units the oldest being 7 years old and still in service. They work great only had one go bad the clock stopped working after 5 years great combo for the price and can be made to fit just about any feeder!
It seems to be solidly built, the entire case is metal. Make sure that the container you will be using allows sunlight to hit the solar panel at the end of the unit, most of the commercial units using 30 gallon containers should work fine. Feeder has worked well so far, and solar panel seems to be maintaining the battery charge.
Works great. Will buy another if needed. Have owned if for a few years now. I bought it for my dad and he uses it every year.
Works great. Unbeatable price. Use it all the time. Easy to learn easy to use very nice product will buy again.
Working great on my feeder. Love it so far. Does just what we need it to do. very pleased I am
Very awkward to install. The housing is long and I didn't have a wrench long enough to hold the bolt so it could be unscrewed. I looked at at taking the timer off to access the bolts from the other end but I would have had to remove rivets. End result, I sent it back.
Answer: yes
