So my understanding and please don't take this out of context; no harm intended, is there's the original Sunpro "Sun Super Tach" then acquired by Snap-on/Actron which produced the Retro line "Sun Super Tach" and finally acquired by Bosch which is producing the Retro line without the "Sun Super Tach" logo on the face. So essentially 3 different manufacturers making the same "style" Tach. The one listed on Amazon would be the 2nd of the three
