I have a couple that @Great In Grass sent me that work just fine. He might be able to help?Just broken mine trying to push it in with my foot.
It was quite thick , so took alot to push it in .
Just wondering what anyone else uses ?
Don't really whant any comments other than recomendations of type and brand, so i can just order one.
I was talking this sort of thing for about a tenner:Can’t remember where I got mine but they are essentially food thermometers to be fair. I found the trick is to buy them two at a time and test the variance between the two. They can be wildy different and I sent two pairs back before they twigged and sent me a matched pair that agreed with a mercury thermometer.
