The density correction is also a tad of a nuisance to use. After the unit has been turned on, if you want change the density setting, you have to press the species button once to reveal the current setting. Then if you want to change it, you'll have to hold that button again for a second or so in order to enter the density change mode. Then you press the button again or hold it to scroll or fast forward to the new density setting. It's not a problem at all if you only have to change the setting once in a while, but if you're in a store with lots of exotic woods and you have to change the setting with each species, it gets to be a little annoying. Maybe some kind of electronic rotary input dial or even a numeric keypad might work better.

Review : I don't know how I ever lived without it! Specific Gravity chart does not cover very many of the exotic, imported, and burl woods that I use. However, it's great for all other woods and you can make educated guesses on my difficult lumber. Every woodworker should have this unit. It's the best I've ever seen!!

Review : I have been using this instrument for four months How did I ever do without this meter... I recently attended IWF-2002 in Atlanta. Wagner, etal were showing their various moisture meters at this show. I took some sawmill lumber to the show with me. I tried all of Wagner hand held moisture meters. I quickly discarded all of them except the MMC-210 and the MMC-220. I decided on the MMC-220 because of the capability to calibrate this meter for any species of wood using specific gravity. It is easy to calibrate and use and does not leave holes in the wood. I would recommend that anyone using saw mill lumber and air drying the same USE this meter. It is definitely the best of the hand held meters.
