Must-Have Diagnostic Tool
If you're dealing with electrical gremlins in cars, motorcycles, trailers, or even lawn equipment, the VDIAGTOOL V210 is absolutely essential. I used it to track down an open wire in a tail light circuit that would have taken me all day using a multimeter alone. With this tool i found it in under 10 minutes.Fast & Accurate:It instantly pinpointed the break under the insulation without needing to strip wires. No more guessing or replacing parts blindly.Simple Setup:probe the wire, and the tone leads you straight to the issue. No training needed—plug and play.Worth Every Penny:Even if it only works once, it pays for itself in time saved. This tool turned a nightmare into a quick fix.Compact and Durable:The kit is lightweight, and the build feels solid. I tossed it in my toolbox with no issues.

Worth the money and the purchase especially long trailers.
It works good it is definitely easy to use, you really don’t even need that long of a cable for the little box as it just connected to a positive and a ground while the wand does the rest, I just wished instead of it beeping and the sound dying off as you loose connection it was the opposite so you don’t have to listen to the sound the entire length of the wire especially if you are working on a trailer to a tractor. It’s a pretty durable plastic as I have dropped already and it’s still together and working just after I found the break in the line I had to re-check it to make sure lol. The cable length I guess does work if you have wires to far from a ground. But it deff reads the voltage in the positive line you are running to see where the break is at.

Good bang for your buck!
As a master automotive technician with over 23 years of hands-on experience majority of my day to day involves in diagnostic work. I'm always on the lookout for tools that make the job more efficient and accurate. The V210 has quickly earned a spot among my daily go to diagnostic tools, especially when it comes to chasing down wiring issues like open or short circuits.Recently, I had a vehicle with an open fuse issue caused by an alternator wire that had broken at the connector and was shorting to ground. Using the V210, I was able to quickly pinpoint the issue without any guesswork. The process was smooth and painless, this tool made a potentially time consuming job quick and straightforward.What sets the V210 apart is its simplicity and effectiveness. It’s compact, easy to use, and extremely helpful for electrical diagnostics. If you do any kind of wiring or circuit work, this is one of those tools that will absolutely save you time and headaches.With all that being said, I do have two suggestions/recommendations that I hope the manufacturer considers in a future update:Continuity Testing with Audible Tone, Currently, the tool uses an LED indicator for continuity checks. Adding an audible tone would allow users to hear confirmation without needing to keep their eyes on the device, especially helpful in cramp areas like under dash or when working alone.Receiver LED Indicator: The receiver unit relies solely on an audible beep, which can be difficult to hear in a noisy shop environment. Adding an LED visual indicator would make the tool more accessible, especially for those who may be hard of hearing or working in loud areas.Overall the V210 is a highly capable and user-friendly tool that’s already proven its worth in my daily workflow. With a couple of small improvements, it could be nearly perfect. I highly recommend it to any tech who regularly works with vehicle electrical systems and it's very affordable!

Good tool for the price.
I am updating my rating because the seller updated the description. Even though this item was supplied to me for leaving a review, the price is awesome for what this can do. If you are tracing wires looking for a "break" in the line, this tool works great. Using the continuity test on the transmitter alone will tell you if the wire is shorted to ground. You'll have to fine the short on your own.Below is my original review. I think it will help you decide if this is what your looking for.I've been working on cars for over 40 years and professionally installing and repairing 2-way radio systems and emergency lights in vehicles for over 35 years. "Shorts" and "Opens" happen once in a while and finding them can be an issue. I was asked to try this tool and found it to be just like the fox and hound telephone tool for tracing circuits except that there is no sensitivity adjustment on this model. Even though the instruction say how to set the sensitivity, its just a volume control. Upon testing this unit I found it helpful with tracing a wire path. However, the wire must be "open" and not connected to any load. If it is grounded in anyway (like a light bulb or voltage probe), the signal is also grounded. The wire must be separated from any harness it may be in at the point of test. If it is among other wires (like a harness) the signal will be lost and not picked up by the receiver. It works great for following a single wire that is disconnected from any load but if you're looking for an "open" the load is already disconnected, so for this instance, the tool works well. As far as finding a short (which is more common than finding an "open"), the tool only tells you that the cable "is" shorted if the resistance is below 10k ohms, It doesn't help you find the short. The tool I use for finding shorts is this,https://www.amazon.com/Tool-Aid-25100-Short-Tester/dp/B000RFLR0U/ref=sr_1_15?crid=1LWSBFPF4EATY&dib=eyJ2IjoiMSJ9.dk9jzsk7AklzpW67YWuSfvJBOOJB1kvQsahd4v-RPD4njmPoXv2WqdObHYt6kxhtUjXoZSQ2IfObBT4GgJEwygFsWJMGtmbYJUrjY8y54RCeb0VpxdmtTDNrXAMisMiX8RvztVk78eZ5msziRn7IwKdwDvtj-7i3-20v4bZ97axA2wSaTSL39fR1mJ_GNIe1D_hzhdnBOqmg3WPYTUW-su0CR8oPMjUzWLzs27-lkQ8e6iPChbGcW31FQdXQf9mROl4n_VfJ1X6mFEVtINXeP-96Nr5_UjxnsFBHiG_2lzc.adG6ka4fwFjragSlkJrmQAgI--gIXwGWE3MsWy4CwFE&dib_tag=se&keywords=automotive+short+finder&qid=1732200540&sprefix=automotive+short+finde%2Caps%2C683&sr=8-15&ufe=INHOUSE_INSTALLMENTS%3AUS_IHI_3M_HARDLINES_AUTOMATEDI also tried using this tool for troubleshooting Christmas lights. I thought I could follow the tone to the bad bulb but because the wires are twisted together like a harness, it didn't work for that either. Every wire had a tone on it just from inductance from being so close to the wire under test.Back to automotive. I tried following an emergency light wire that was in the same cable with 3 other wires. All four wires would pick up the "tone" from the transmitter all the way through the cable. If I shorted any of the 4 wires to ground, the signal would disappear, even from the wire under test. So, unless you know the exact wire you want to trace and find a "break or open", this tool may lead you in the wrong direction. I can see this tool being handy in some situations but if you are a serious trouble shooter or mechanic I would use other methods of finding open's and shorts. Also, some circuits can test fine until you put a load on them due to a weak connection or corroded wire. This tool requires you to remove all loads on that circuit for this tester to work. So the fault will not be found without a load. Always start your troubleshooting with a good visual inspection

Huge time and sanity saver!
If you do any installs in your vehicle this is worth its weight in gold. I originally bought the pro kit and found the only thing I was really using was this. So the pro kit stays in the shop and I picked up one of these to carry around. This has saved me countless hours tracing wires on a used Jeep I purchased.
