Just got the newer marine version Hanna checker for Christmas.
I will admit that I got it on sale and used a coupon... (BRS sometimes runs sales on them and I had it sitting in my cart for a while so they sent a $5 off 50 coupon.)
Pro: fast results in simple easy to read style.
no conversions
It seems consistent
the 2 times I have run tests with it the first result matched the second test both times I have used it (4 tests total 2 on each vile). For what its worth I ran it at the same time as ELOS test kits and got very similar results.
Con:
I think there are only reagents for 25 test before you need a refill.
Its expensive to the point where I wouldn't buy it if it wasn't on sale.

I have a question. I got the same for Christmas. Black Friday special. 35.00 each. When the 3:00 minute timer is over do u press and hold black button or just press it once. Mine keeps resetting before I can get a read.

I am not sure we have the same meter. Could you be thinking of the PO4 or PH meter? I never had a 3 minute timer on the Hanna dkh meter. I pressed once to turn it on. Then again after the loading a water sample to zero out the meter. Then once more after taking the vile out and putting reagent in the vile. The reading took less than 20 seconds after pushing the button the 3rd time.
To be clear I was talking about this meter:

They always vary in color. I'm not a fan of them any more. The only way I have found where to stop is to compare it to a control test kit. Once I fetermine that color I try to remember it. Another way is to look for the color change, remember where the dropper is, drop one more ml, repeat until you get. I change in color then go up 1 or 2ml for your reading. It's a PITA.
The Calcium and Magnesium tests are great. Although the Magnestiumbtest takes too darn long the results are easy to read. There has to be a better way.

Do you guys out it on a white piece of paper? Mine color change is very clear and decernible. This is probably my 4 test in 2 years and did have to send one back once for reading off. Customer service was very helpful and only needed the lot number ect. I do check it against my hanna checker about once a month and a lfs every so often. I despise how clean the hanna vials must be to get an accurate reading. I have microfiber towels by my tank just to try and get them perfect.
