Packs a Punch with Features (Best Bang for Buck)
Best bang for buck when it comes to electrical probing. Back in the day I was using Power Probe's equipment and yes it gets the job done but with this Autel one it changes the game. With all the functions and features that this probe brings it's needless to say that electrical diagnosis will get easier; of course if you know what you're doing. In the department of design it feels familiar as the one from Power Probe since the design of the body is quite similar. When it comes to build quality I can certainly say that it's sturdy and feels high quality in the hands. When used it greets you with different options to measure voltage, ohms, continuity and other electrical diagnosis. Something that threw me off from this was the cycle duty which I genuinely did not expect it to have so I don't really have to use a multi-meter. Needless to say, whether you're a mechanic, electrician or something along those trades this tool is definitely an amazing buy!

Great for electrical diag tool
At first I was skeptical about buying it, I’m glad I did. It’s well built and makes diagnosing easier. It’s also got good amount of wire to reach the back of cars. Would buy again !

Useful tool but resistance function is VERY INACCURATE
12V/Ground detection and supply features work perfectly. Very reasonably priced compared to competitors. However, be aware the RESISTANCE MEASUREMENT function is very inaccurate. For resistances less than 10 ohms the measurement reads ZERO, which will really confuse you when trying to troubleshoot. For higher resistance measurements the error is over 15%. Stick to a multimeter when trying to measure resistance.
