Default Mash thermometer - digital w/ probe, what do you guys use?

Looking to get one of the typical digital thermometers with the metal problem attached to a cable. Saw some dude on Youtube use one in his vid and would like one myself. I know the probe isn't meant to be fully submersed in the mash as the end that meets the cable typically isn't water proof. But the probes seem to usually be a few inches long meaning I can hang it down into the mash and hold the cable while putting the lid on to keep the probe hanging at length - just what I saw the guy do in the vid.

Anyhow, there are many brands and makes of digital w/probe thermometers out there and I just want to see if any of you have any you've been using for a while that you recommend. I do not want a thru-wall or anything other than the digital/cable/with probe type at this time. Just trying to see if there are any tried and true one's out there that I can confidently go ahead and buy.

I've used this http://www.amazon.com/gp/product/B00...ce-full-site=1. Accuracy should be checked, though. I use a Thermapen nowadays.

Fluke could work. You can use measures J, K, T, and E-types of thermocouples. Cost is higher but they last a long time. But I am an industry guy and brew with the equipment I have at work.

I have seen a vid with a guy using the digital thermometer with the cable and probe and he had + or - 6 degrees written on it from his calibration. Can't remember which direction. Either way I question the accuracy of them. Always calibrate! Cheers.

Only "recommended" cheapie I know of is the CDN one, and that doesn't have a remote probe, (btw, I chuckled at how your autocorrect turned "probe" into "problem" in your original post...hilarious, and pretty true).

Whatever you go with, I've recently been thinking about sealing up a probe with silicone. I mean, it's food safe, handles temps up to like 500F, and easy to apply. The only one I know of is the DAP 100% silicone sealant, (here, but also at probably any hardware store). Seems a lot more permenant than the hokey "aquarium tube and vaseline" sealing method....and then you don't have to worry about getting it wet...

I guess it was my error typing away too fast or something cause I wasn't on my phone at the time.

Is the risk of damage that great not sealing up the probe end - ok, just typed "problem" again so apparently it's me... I got some glitch mentally that occasionally types problem instead of probe LOL. Didn't even realize that till typing now. Anyhow, if the probe is suspended just enough for the steel to be in the mash and no further does that still pose a risk?

OK, looking at Thermoworks, they have a waterproof PTFE (Teflon), Type K probe used for dishwashers, freezers, etc. See here (about 2/3 down the page): http://www.thermoworks.com/products/probe/tc_wire.html. The downside is cost -- $29 for the probe, ~$70 for a meter.
