I've gone without a tach for several years now, but I think I really need one now that I've bought my first 4 stroke. There seems to be several brands on the market. Globee intellitach, Tower Hobbies, Hanger 9, etc. Which tach are you guys using and what are your recommendations. Do they all offer similar accuracy? I definately want a digital tach. Let me know.
