Its not cheap at about $90, but hands down is the best and if it saves a few good steaks, it pays for itself.

Absolutely perfect accuracy, reads within about 3 seconds and makes a tiny 1/8″ hole so as to avoid any unnecessary loss of moisture by poking the food.

All top end high end steakhouses make this little guy standard issue.

Other uses include stick it in a baking potato. When it hits 210deg, you know you have perfection.

You still want the oregon type unit for long “slow and low” covered indirect cooks (I highly recommend the Traeger Grill for that, thanks Deb!) as every time you open the lid, you drop the temperature and mess with perfection.
