I don't trust anything other than the number of Motorcycle's and domestic production.
I want to use a device that I'm not ashamed of.

If there's a problem with the LCD or operation, it can be repaired, but then I'll buy another one, and that's repair pricing
I'm not bad at wearing the solder on the base, but I'm not good at it
I can't imagine buying another one

I purchased it because it is necessary at work.
I bought it in 2016, but now it is double the price - - -
Analog is also used, but initial adjustment from Gauge set is necessary, the fluctuation of the pointer changes according to the adjustment, so doubt arises in accuracy, but Digital has no room to doubt the number unless it treats roughly.
Since I was using it for many years in my old work place, there is no doubt about handling.
The feeling of matching exhaust pressure and Engine sound with the number of revolutions is also Large thing, but equipment is necessary after all at work.
Purchased and correct answer.

Although he had been thinking from before that it wanted, it was not able to plunge from it being expensive.However, purchase since CR carburetor purchase is carried out and it adjusts with attachment.Unless operation is also broken simply and legible, it uses for a long time.It is kind, if it checks and tampers with using it also at
famous Shop and one person has it some between good one.
