  • GREAT POWER CIRCUIT PROBE TOOL
I am a fleet mechanic this power circuit probe makes my job easy to test electrical circuits you can check DC voltage/ AC voltage / Resistance. I also like it that it comes with 20 feet extension cord you can connect to the battery or power outlet. to test taillight trailer connectors, power up solenoid, apply power to fuel pump, fan motors relays. check for bad ground, find short Circuit. Compared to other brand this is this best price I recommend to buy from this seller ***** ... show more

  • Amazing Tool!
This product is a must have for any electrical testing! I am very impressed, it’s lightweight and simple enough for anyone to use. It comes with two different options for connecting power, using a 12V outlet (cigarette outlet) or using the alligator clips provided for positions and negative battery terminal. The positive and negative connectors are shaped, so it can only go in one way. This tool can measure voltage, resistance, current, as well as check continuity and polarity! The hard case is sturdy and provides sufficient protection and there is a built-in breaker for overload protection to the tool (side button in photo). The cables attached are very long and this also comes with an extension cable that provides an additional 20ft, if needed! You can easily work from front to back on your car/truck/trailer. This tool certainly compliments anyone’s toolbox! ... show more

  • Well worth me spending more money for this tool
There are several things that stood out to me, first was the overall quality. Nothing light-weight and cheap. The cables were heavy duty as well as the clamps and connectors. The tool felt great in my hand and the probe was thin enough to get into tight spaces but not that thin that I felt I would break off the tip. The additional cord is nice when I am working on two cars at a time in the garage. No need to swap the battery connectors back and forth. I really like the tone difference for the ground and hot. I know where I am without even checking the screen. I knew about the power up feature when I purchased this, meaning the ability to fire up a component with the second lead right on the tool. This has come in handy so many times when doing a diagnostic. A feature I did not have on my last probe which saves a lot of time not having to mess with additional cables. The screen is clear and the overall operation of the tool is simple. Just connect it and you will discover the features as you need them. I have owned Autel scanners in the past, but this is a step up. It feels more like the pricey testing equipment I used when working at the dealership. I am very happy with this and will be making sure to check this Autel brand out before my next tool purchase. ... show more

  • Excellent price and excellent quality…
Excellent product and works as the higher dollar brands. I used these probes for so many things. The biggest test for me is parasitic draws. This is an excellent tool for that. Voltage drops, Charging faults and lights and virtually any other electrical issue that you can think of. Service after the sale and quick shipping. Sturdy case, sharp probe end, an extension lead and battery clips. All packed nice and neat. I use in a commercial setting daily and can tell you this is a great tool! ... show more

  • Almost good one major flaw: But excellent customer service.
I do like it and the price is good, however it has one major flaw in my opinion. It provides a tone for + and - and this is a handy diagnostic feature for hard to reach places. The flaw is that if you are on a circuit and getting for example a - tone and that circuit goes to + the tone will not change, it continues with the - tone. This is a feature I used a lot on my other brand tool to tell what a circuit was doing if I could not physically see the tool. I really don’t like this, but the tool does function well in all other aspects. UPDATE: Autel reached out to me and said they are sending this to engineering to try and update tool, hopefully that will happen. They provided excellent customer service and offered me options to make me satisfied. ... show more
