The Dickey John Mini GAC allows you to accurately know when a field is ready to harvest.  A moisture tester can take the guesswork out of knowing when the harvest to maximize you profits.  Moisture contect is the universal factor used to detmine the price when traiding grain.  The ability to know the moisture content at various stages of growth, harvest and sale can mean extra dollars for you in the season.  You've worked hard hard to produce a solid crop so make sure to maximize your efforts with an accurante moisture reading before harvest and before selling.  If you're not using a GAC product on the farm to test moisture, you're losing money—up to $1.42 per bushel of corn.

Customer Reviews

Arrived as expected Review by Greg

The unit arrived timely and ready to use. Rural King had the best price I could find. The unit occasionally gives me an error reading for no apparent reason. It seems a bit touchy. Cool grain readings were very accurate. Hot grain was not as accurate.

Did test moisture correctly twice Review by Rock

Took to elevator to check. Only could get two tests to work. Had followed instructions to the tee. Flow of larger soybeans beans did not work well (need to have higher drop over cone to alleviate this problem)
I was very disappointed with this unit. It had the makings of being a great product....just fell flat. I do a lot of research plots for a seed did not measure up for me and I have used other Dickey John product in the past

The first moisture tester I recieved tested the grain at 10% more moisture than the local grain elevator Review by Carl Chambers

I ordered a Mini GAC moisture tester from Rural King and tried to use it and it didn't read the moisture correctly. I was cutting soft white wheat and it said that it was at 18% moisture when I took it down to the local grain elevator their moisture tester said 9% Dickey John Support was very good at getting back to me and they said to return the product and get a new tester hopefully the tester didn't get mauled too bad during transit. I follow all of the directions to a T and hopefully it was just one bad cell. I cant say if I would reccomend the product yet that has yet to be determined.

The Mini GAC works great to get fast accurate moisture readings. Review by SCOTT

Have used on a couple of occasions and it works good to get moisture and temperature readings. I would consider the version that gives test weight if I were to purchase again.

Very good bang for the buck Review by Farmer

After shopping my local stores for this moisture tester, they were not close in price even with the sale price. After ordering the product was shipped the same day. Very nice.
