Product Manual
Dickey John Mini GAC PLUS Grain Moisture Tester MINIGAC1P is rated 4.7 out of 5 by 49.
Rated 5 out of 5 by from I had ordered the Ag-MAC Plus first, lured by the price but sent it back when I couldn't get it to work correctly. Testing was timed, so if you were not fast enough, you would have to start all over again. Don't be fooled, these units are not equal, so spend a little more and get the Dickey John Mini GAC Plus.The Dickey John Mini GAC Plus is very easy to use. You press a button to continue thru each step. I took it into one of our bins and took multiple readings. It will measure the moisture and test weight about as fast as you can put the samples into it. I can even take readings without setting it down! This is a very nice unit and highly recommend it. The only part I don't like is it takes expensive 9 volt batteries, but I'll put up with the batteries for the superior design.

Rated 5 out of 5 by from I use this product daily with field trials on soybeans, corn, wheat, and sunflowers. All the test weights and moisture are within .5%-.5lb of the local grain elevator. Saves me a lot of time and miles. Just do the test in the field without having to run to town to the elevator to get the final weights and moisture, therefore I can give accurate yield results to the customer right there in the field. Durable carrying case also. Very simple to use.

Rated 5 out of 5 by from Well just bought it in January so won't really put it to use until after my 2015 corn and bean crops are picked, I am a small farmer and dry all my corn and looking forward to this working as good as all the reviews I have read on it....used others over the years and they never have been accurate? hope this is finally the one I have been looking for. joe

Rated 3 out of 5 by from Not cheap, but then high quality tools never are. Every time we checked it against the elevators moisture tester it was always within .5% across many moisture ranges. It may not be the handiest as it is larger than most moisture testers, but still small enough to ride in the combine or tractor cab. It will be the tester we grab when we want accurate moisture readings.

Rated 4 out of 5 by from I have checked our new tester on wheat and flax so far. I got online and in a half hour or so had added the other crops that we raise in our area. It's been right on the money with our local elevator each time I checked it for accuracy. I'm already way more confident in this tester than the one we have used in the past. It is a quality product.

Rated 5 out of 5 by from I am very happy with the product that I purchased for my husband. He got it for Christmas so obviously he hasn't used it yet. It is in a nice carry bag and is light weight. The product was easy to find and to purchase and I felt safe ordering from this company with the great security.

Rated 3 out of 5 by from When we went to order this product the pricing was extremely miss leading. Apparently your old sales price had not yet been removed, so when the product was added to my cart, the price went up. IF you cant get your sale prices down quickly maybe you should still honor them.

Rated 5 out of 5 by from My husband wanted his own tester for awhile was his Father's Day gift, he was very happy. I think every time he has used it he calls me to to tell me how much he loves me. Best purchase I've made in a long time. It was just what he wanted and needed.

I would like to buy this grain moisture tester. Do you ship to Europe? If so, then what would be a cost to ship it to Lithuania ?

Looking forward for your answer.

Will this test moisture for green Hops?
