Received the Digital Laser Tachometer last week and have been running it through some test on my Airplane. The unit feel solid and it uses a 9V battery. The package does comes with a nice pouch and in the pouch it include some reflective tape. The Laser beam is quite broad and not focus to a dot which is good as it would not burn your eye if you accidentally point to an eye but do be care full as the beam is still quite bright. You would need to cut and stick a piece of the reflective tape to one of the airplane prop and point the laser beam to the general area where the reflective tape is when the prop is spinning. The unit remember the max and min speed in rpm.

This is a perfect tool when you should adjust the ignition on your car at the right rpm. Easy to handle and a very good quality. Very good Bangood.
