Nice review. I just purchased this unit yesterday after experiencing storm damage inside my home. It worked fine helping me determine how much drywall to remove. Of note is that the instructions state that it will measure up to 3/4”. It doesn’t state that the material must be 3/4” thick as indicated in your review.

[@brandonwa2498]

The reason it’s overloading on masonry is because using it on top of aluminum table its to much metal behind its emi based I believe

[@calvinkrist5672]

I don't know how it works for masonry, but at least with wood, moisture content can go over 100% if the water in the wood outweighs the actual wood. Lots of fresh-cut green work is over 100%.

[@aaronsrapidreviews]

That would be a lot of water, but I suppose that's a possibility.

[@regibson23]

OL is typically over limit not overload.

[@soothingme]

Can i recalibrate this. . Mine is off turns on at .8% should be .0%

[@debandmike3380]

wait, are you saying the same bit will both loosen AND tighten the battery lid screw? that's incredible!!

[@stevenroscoe9877]

The 3/4” requirement for drywall also threw me off. The manual contradicts itself. At one point it says it can read material up to 3/4”, but then also says the material should be at least 3/4” thick. Which is it? I agree this is skeptical at best for measuring drywall that is actually in a wall.

[@markarita3]

I know, right? That 2nd part (on page 5) really messes with you. It's basically saying it's taking the reading at precisely the ¾" depth mark, and if your material is thicker, then it won't be able to read beyond that point...and if it's thinner, then add a spacer btwn. the meter and material being tested. VERY strange.

[@csimet]

Nice review, but did you test it on other masonry? Just to see if the meter does in fact detect lower than 100% (overload).

[@1Ninjago_fan]

Could have mentioned an alternative or 2.

[@CaptSeeryus]

Been using it for a while as well, doesnt really work on concrete slabs, but ok on stone or quartz/marble countertop..etc Drywood and wood, is fine. If there is a beam behind the drywall though, it does get weird or overloads.

[@markharris5190]

Here's is my understanding of the displayed % readings. It is a relative reading. If it reads 10% then the weight of the water in the wood is roughly 10% of the weight of the wood. If the weight of the water in the wood is more than the weight of the wood (that being the actual weight of the wood alone if it was dry), then a reading of more than 100% is possible. I think that's why you are getting OL on the masonry. It is really wet so the weight of the water detected in the masonry may be heavier than the masonry itself and thus measure at greater than 100%

Thanks for the review, just for future reference brick, mortar etc. materials are pronounced: mason - ree , not mason -air-ree ( no “a” sound)

[@Hakuna_My_Tatas]

Masonary 🤣🤣🤣

Hmmm... I'm sure you are right, but I guess I say it both ways (like Caribbean... One way for the location, and another for the Disney ride/movies)... I wonder if it's regional (I have lived all over).

[@nelsonbrum8496]

I came here to say same.

[@BallsWalls.Renovations]

How do you like it honey... "Missionry"

[@z4900]

They have that scissor attachment in dewalt?🤪

[@nelsonbrum8496]

Yes, it attaches to your impact driver.. DWASHRIR if you're patient, you can get it for $40. I have two, home and work.

[@Trashed20659]

The accuracy of cheaper devices like this is questionable, considering very reliable units can cost 30-50 times as much. As long as the readings are consistent however, one could use this by referencing materials they KNOW to be dry as a base line. Some don't like the need for a screw to be removed when changing the battery, but using this outside, assume that it will better survive being dropped into a puddle.

[@williamm.3612]

what about using this for boats?

[@sqqqrly]

Or RVs?

[@HeliRy]

For wood, I hate meters with pins. So it’s either this, or pay 10x more for the Wager Orion. Not much of a choice really 😂

[@adamthewoodworker2571]

Hi, I have a quick question. For a moisture meter, it says it'll go .75in thick. Does this mean it would not be good if you want to read the moisture of 4x4 studs? Or would this still work fine?

[@aaronsrapidreviews]

I think it would work fine

[@debandmike3380]

obviously you don't know the first rule of moisture meters. You don't set the material down on metal.

[@pattywattyann]

That package....omg....near sliced off a finger. Good angry start! Then it doesn't stay on...back to Amazon

[@aaronsrapidreviews]

I don't know why manufactures use packaging like that

[@gleaful1202]

To thwart thieves.

[@joshuabray37]

It's crazy how hard it is to open. I hate that kind of packaging. You shouldn't have to use power tools or Samurai swords to open this kind of thing... I had to use a REALLY sharp/big knife (and almost cut my finger off).

[@nelsonbrum8496]

​@@joshuabray37I use a hook blade box cutter or metal shears, whichever is closest.

[@joshuabray37]

@@nelsonbrum8496 yeah, now I keep a pair of good scissors in my shop. They work well.

[@AL_Marx]

it's 40$ what do you expect

[@aaronsrapidreviews]

Something better

[@AL_Marx]

@@aaronsrapidreviews spend more you will get something a lot better like a FLIR but i use this at work for leaks and it performs great

[@Robert-yp9zs]

Major points loss due to: indestructible packaging (totally needless) and no protective case (needed for precision instrument). If this was a $7.99 tool, maybe. But, this is not a $7.99 tool.
