VDIAGTOOL V200 PRO Upgrade Kit Automotive Power Circuit Probe Tester with 30PCS Back Probe Kit, 12/24V Electrical Short and Open Circuit Finder AC/DC Voltage Test Activating Component 40Ft Cable

I tested the VDIAGTOOL V200 PRO tool tracing out wiring issues on a couple different utility trailers and a pickup truck with a short. Now I had other ways to test the wiring but this tool made it so much easier. I love the fact that the extension cable allows you to reach a long way. It has multiple ways to get power to the tool for testing lights, putting power on wiring with the push of a button.The breaker finder worked fine once I replaced to battery it came with. The included battery was dead. I have several breaker finders for 110 volts. This works as good as them up to 24 volts but using one is something you have to master the art of. I know people complain when things don't come with batteries but I prefer they don't so I can buy good quality ones.The accessories are a big plus just wished they had included a better bag or plastic box to keep them in. I bought my own plastic box, a soap bar holder to be exact as they are cheap and I use them for a lot of smaller items.Now most people who would buy these types of tools generally know how to use them. I tested this in a few different ways like when it got hot sitting in my truck and putting it in cold conditions. Yes, there are important to me as many times I carry a few tools and forget to take them out. The plastic accessories held up well in both temperature differences.The quality of this tool is very good in my opinion and is well worth the money you spend. The accuracy of the voltage readings were fine and verified with other voltage meters.

The media could not be loaded. The VDIAGTOOL V200 PRO is an impressive and affordable alternative to higher-end automotive circuit testers like the Power Probe. It delivers a full suite of diagnostic capabilities—including voltage, continuity, polarity, resistance, and wire tracing tests—making it a versatile tool for both professionals and DIY users.What sets it apart is the value: it includes a comprehensive 30-piece accessory kit, and thoughtful design features like a long extension cable and multiple power options significantly enhance usability. Real-world testing across trailers SUV confirmed its accuracy, durability, and ease of use.I used the Breaker Finder successfully in recessed compartments of modified utility trailers that I would have otherwise had to disassemble to get to the wiring. I believe that finding broken wires in this manner saves so much time. I have also used it to test LEDs in malfunctioning headlights. I imagine that this will aid in hard wiring dash cams (several upcoming installs) as well.For anyone seeking a reliable, cost-effective solution for automotive electrical diagnostics, the V200 PRO is a smart investment.

I recently purchased the VDIAGTOOL V200 Pro to help with the install of hard-wired dash camera kit. (If you don’t have a dash cam – get one! Hard wiring it to you battery cleaner than plugging it into cigarette lighter/power plug, and pretty simple with a hard wire kit that replaces one of the “always on” fuses). The V200 circuit tester allowed me to find quickly find out which fuses had constant power from the battery and which fuses are only energized with the key to the on position. The tool provides auditory and visual indications, and the screen tells you exactly the voltage of the system – see picture. (You can also use the tool to check the voltage of the battery quite easily). I’m only at a DIY level but will likely be using this tool again to fix the wiring on my dad’s utility trailer. Besides testing circuits, the tool is also capable of diagnosing electrical shorts, open circuits, parasitic draw, etc etc. The tool has four modes Luckily, I don’t have to use any of the advanced functions yet but good to know that it’s there.The whole kit is pretty comprehensive and more than I need for my current project as VDiagtool offers simpler/cheaper kits, but I’d rather purchase a comprehensive kit and have additional capabilities in case I need them in the future.The Pro kit has several different connectors, a cigarette lighter adapter (can be powered by the battery or the cigarette lighter/power adapter) and has a 20-foot power cord to reach the front or the rear of your vehicle. The instruction manual is simple and straightforward (allowed me to use it to find always on fuses). However, the using advanced features are not explained in the manual...if you know how to use them I'm sure it is intuitive enough or seek youtube/internet for answers.The case is compact and efficient, you’ll have to carefully rewrap all components to get everything put back in to close the case. Good build quality and should last as long as you don’t throw it around/abuse it.The build quality of the testers is solid and does not feel cheap and flimsy. Audio, screen, and lights are clear and useful. The connections fit tightly together and won’t fall apart.BL – this tester exceeded my expectations and helped me save money with DIY projects.

It's not as user friendly as a power probe. That being said, once you figure out how to use it. You can use it just a fast as a power probe. My only problem with it, is the case is really too small for every thing. It has everything a power probe master kit has for a 1/4 the cost, but not enough room to cleanly put it away.
