I have an older one, you will really get a lot of use out of it, mine also has an aiming laser. Find the dead cylinder in a misfiring engine by pointing it at the exhaust manifold. See if the heat is on coming out of a high duct. Check accuracy of thermostats and temp gauges. See if your car radiator is working by seeing temp drop between bottom and top. Is your PC chip cooling properly. Can I pick up that piece I just welded. Are the trailer bearings working OK (One wasn't and was spinning on the spindle, I could also have just put my hand on it but still......)
Dang it is cold out this morning here in California, must be 42 degrees in the garage. Hopefully it will be 72 later, hope you guys in the midwest are enjoying your winter. (I've done my time in Chicago, thanks)
