Is the temperature taken along the entire shaft of the probe or just at the bottom. I would like to take soil temps at 2 and 3 inches,

Hi Terrie, Yes, you can just use a portion of the shaft to get the soil temperature. I use it in the shallow greenhouse planting medium as well as outdoors to check ground temperature before planting seeds.

It is taken just at the bottom. There is a notch 2 inches from the tip of the probe that indicates how far to insert it into the soil.

It says insert into the soil 2 inches. It's marked on the shaft but I have pushed it down 3 inches. You shouldn't have any problems taking temps 2-3 inches deep.

I don't know for sure. I just stick it into my compost that is 6 " deep and I get a reading at any depth I place it in.

temp probe is very accurate to a tenth degree. don't if it's unique to the unit but then You don't need another one.

Hi Jared, The probe tip is about 5 1/2" from the bottom or 4.25 gal worth of liquid. Hope this helps. Barley & Vine

The temp selector only seems to work well if the pot is filled to the 1 liter mark. If its only half full I can hear it boiling. I have never put a temp probe in to see exactly what the temp is though.Ed: So you made me curious, I heated water at the low, middle and high settings. I then poured the water in a cup and over my digital instaread thermometer. The temps were on Low-155F, middle-191F, High-206F. Considering I could see the water boiling on high I assume the water is losing about 6 deg as it pours out but the temp in the cup is what your tea bag or coffee would experience.

The probe is probably around 6 inches. From what I could tell it is the first 1/2 inch to 1 inch that registered the temp.

I ordered extra probes with mine but haven't had a problem with the ones that came with it, I put heat shrink where the stainless wire meets the probe and have been smoking what seems like every time it snows without issue

The probe is very accurate. I think the probe is unique to this unit, but any 2 wire probe should work with it. Don't forget the temp on this unit is only in Celsius.

For what you're doing, thermometer placement would be critical. You'll have a much higher temperature gradient in soil than in compost. You might try inserting at a shallow angle to get more of the probe at a given depth.

I would say about a foot down. I never use it on the highest sensitivity because it picks up lots of metal fragments and there to deep to dig. Sometimes it beeps and there's nothing there when I dig, so whatever it is, its got to be pretty deep down. I would also recommend a hand metal detector to shift through the dirt, because it takes a while to separate the earth to find a coin or ring.

You shouldn't have to "mash" anything, except potatoes ;) You press the button and insert the probe (at least that's how I do it) and the read-out will provide the temperature. You should not have to hold the button down. I've been incredibly satisfied with this item.

I'm using mine in very sandy soil; and it has a tendency to dig in to axle depth, no matter what setting, if I don't take care. That said, on the shallowest setting I can, with caution, hold it to about an inch...

The deeper I get in my pile the hotter the temp. I believe the metal probe transfer heat to the gauge. So it's the tip that its reading thru but it takes time to warm up thur the

I've never tested temperature on soil, but I don't see why not. It's just a very long meat-thermometer-looking temp guage.

I'm guessing something is broken, as the thermometer should give an accurate reading of the ambient air temperature whenever you don't have it in the compost pile. I doubt that you live in a place where it's always 60 degrees. Did you ever drop or bump the thermometer?

While the probe reads temps at the very tip, the first 5/8ths of the probe is thinner and it does read that far up. Above that point, it doesn't register any temp.

If you have tough clay soil it is difficult to insert. The probe is strong, but will start to bend if you have to use too much pressure.

Peg Leg, please re-read my original answer to you. I added more info for you. Even the description on Amazon states this thermometer has a 2.9" probe. I was close!!!
