This product emits a laserbeam and registers the rpm based on the reflection of this beam. This allows it to work on much further distances than normal tachs and so can keep you safer!
There is also a ample supply of reflective tape.
I use this to read the rpm of my large props from over 1 meter (3ft) away!
Sticking a reflector on your cars axle allows you to read the rpm there too, without sticking your hand down into the engine while it's running!
If you don't have a tach, get this one! Safe reading distance and good accuracy makes it the perfect tool for any hobby-use.
