They have a lot of stuff on sale right now but this one seems to perpetually be on sale. It is everything they claim. I've been recommending it for years since I bought my first one. I threw away most of my other thermometers except the Brinsea Spot Check.Just ordered one...they are on sale!
My food thermometer is my most accurate too...
....but it is not instant read, nor can it be calibrated.
I hope it really will read in the 5-6 seconds they claim,
will be of much help in the kitchen as well as the incubator.
Thermoworks has another version of this that is 24 inches long I use for composting and scalding chickens.
One drawback I've found with the instant read feature is you see the dramatic temperature swings as the heat element kicks on and off with a stc1000 thermostat controller attached to a multi-directional fan/heater.
The fan blowing across the thermometer in a big cabinet will run it up quickly.
In a steadier incubator like a good table top model or a Sportsman it is more useful.
