One of the best tools that I have purchased in a while. This unit does it all from testing voltage to powering items. I have used this tool several times and it works great.

Why didnt someone invent this product when i was a mechanic years ago? Probably cause cars got very complicated. If you work on cars today you NEED this tool.

This kit was a bargain when I bought it for $75.01 on July 2, 2017; a week later it has gone to over $88.00 from the same vendor on Amazon. There are other versions of the PP319 kit on Amazon that accurately show you what you are supposed to get, some cheaper and some more expensive for basically the same thing. The picture of this kit is misleading, in that the standard power probe and black plastic carrying case are left out of the picture of the product. This was called to Amazon's attention, but no action was taken. The screw-on probe is packaged in a separate cell within the plastic bag that contains the cables, etc. - so don't overlook it when examining what they sent you. In addition to the power probe unit equipped with the standard cable, the kit comes with the standard probe, a 20' extension cable and a separate connector for the 12 volt lighter/power socket inside your vehicle. All of this is housed in a sturdy black plastic case. The power probe is powered completely by the vehicle's battery, and won't work until it is correctly connected. An instruction book is included. This model has been upgraded to the much more expensive 3S unit that has a better readout and some other features; use your own judgment to decide if the upgrades are worth the expense. If you are a professional, they might be worth it.

The Mechanic at work knows I tinker on some old cars and also do my own repairs showed me the power probe and I knew I had to have one. Awesome tool.

best tool on the market. do not buy power probe 4. huge disappointment
