Looking for the pros and cons on the available tachometers out there for chain saws. Do the higher priced ones really worth the extra costs or do the middle of the road ones work just as well.
The DTI Fasttach has worked great for me for a couple years now. Factory direct it’s under $100, or used to be. Handheld Tachometers | Design Technology, Inc., Home of Tiny-Tach
I have a oppama one that is several years old and it seems to work fine. Look for one with a fast sampling rate.
