  • Great tool
Size: 3V-48V
I bought this tool for the digital readout - the LED display was good and bright and easy to read - it was also accurate < i compared it to a multimeter and the readings were spot on - the alligator clip is of the right design to allow for multiple applications and better connections < unlike the usual tiny clip connectors that other testers come with - i have used this tool on different applications and have now found a very useful tool that does the job of several . The tool design is great and appears to be of high quality - the price made this an excellent value I will definitely look to this company for future tool needs Thank you for a great tool , Rtm ... show more

Size: 3V-48V

The accuracy was so close to that of a fancy meter that an electrician was using on my truck that I didn't even bother using the fancy meter when testing the battery. ... show more
