So far so good - seems to be working with my O-300-D cylinder and EGT. Fit right in the panel. I like the high-viz orange tips on the needles.

Fit right in the panel. Seems to be working with my O-300-D. I like the high viz orange tips on the needles. Difficult to independently verify the accuracy but I suppose that’s true of all of them.
