GTC GTC505 Engine Ignition Analyzer - Spark Diagnostics and Tachometer Readings for Marine, Motorcycle, and Automotive Mechanics, General Technologies Corp

I had this tool now for a while I'm impressed with it it works very well. It's great for a quick run and gun misfire chase down it's well worth the money. A great product from Canada! I'm sure this is a US seller support the US in Canada! The build quality is great the functionality is awesome! I think the price could be a little better but it's worth the money!

I've been troubleshooting a problem with my wife's 2010 Navigator, which has had me poking at COPs for a while, now.When there's a misfire due to a failing COP, you don't need this tool to figure out which one -- the code that's thrown will tell you which cylinder. However, if the engine idles rough and there is no code for misfire (not yet?), or maybe you *think* you've fixed the problem and just want to be sure, having a tool like this within easy reach is extremely handy! Just point the probe over the top of the coil, and like magic, you're seeing spark voltage, waveform, and burn time instantly.Or... maybe you didn't fix anything and the engine is just magically running smoothly now? Use this tool to check the suspect coil's operational characteristics, then compare it to the other known-good coils to determine if what you're seeing is normal. Maybe the suspect coil is firing every time now, but the voltage is way low, or the waveform shows a wide, trashy waveform... now you know the problem didn't actually go away, it's just hiding (and you're not crazy).I've used this tool only a handful of times (same vehicle, same problem), but enough to confidently say that it works every time -- I just hold the probe over the top of the coil, and I get a clear, consistent reading. I don't have to fight with it, don't even have to worry about whether I'm holding my tongue right (haha), it just works.The unit itself feels solid and substantial, and there's nothing "cheap" about it. It's dead-simple to use, the display is clear and very easy to read, and I get the impression that the information is accurate and reliable. Even after it sat in its case for several months (since I last used it), when I went to use it again the other day, the battery was still fully charged and ready to go.The only downside is its price -- while every "shade tree" mechanic would benefit from having this in their toolbox, it is a bit cost-prohibitive. Given what it is and how it works, I can see why this isn't cheap. But if you're stuck on an ignition problem that you just can't figure out, or one that keeps recurring after you've fixed it, this might be worth the price to save yourself a ton of time (and your sanity).

Awesome tool!!! my RECOMMENDATION FOR SELLER AND PRODUCT.Working well, fast diagnostic, easy for handling, display big enough, buttons well, also completely is quality build, intuitive software...and so on.Only one objection, extension cable to be included in kit, and maybe bigger box.

This thing absolutely blows me away. I saw many youtube reviews on this, and people raved about it so much I thought i'd get one for my Outboard marine shop. Boy was I wrong.... its even better than advertised. Some people are unhappy that spark voltage jumps around a bit, but clearly just a misunderstanding of how ignitions work. Its not the reading that matters: only that all cylinders are within eachother's range. In addition, you will immediately tell if somethings wrong not so much by the voltage view, but by the "chart view" feature that basically acts like an oscilloscope to detect big voltage spikes (bad, btw). being able to set idle speeds in the water without a clumsy digital timing light is a MASSIVE plus for my line of work. Its just fantastic. Cylinder drop tests are a thing of the past. I find myself looking forward to a customer bringing in a motor with no spark on a cylinder or 2 just to use this thing!

I have one that is six months old. I have used it several times and love it. It stopped working at six months. Will not power on. I ordered a replacement and got it next day. Brand new out of the box and it does the same thing. I sent it back for a return. I contacted the manufacturer about the first one, I'm sending it in for repair. The manufacturer is well aware of these issues. I will see what happens.

Works
