I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…

Very happy with our new tachometer!
Very accurate readings! The “analog” style LED arc means at-a-glance tach readings that allow the pilot to keep his attention where it matters, not reading a gauge. The digital readout is great for maintenance checks and mag drop tests.
