HantekHT25 Auto Ignition Probe Automotive Oscilloscope Probe High Voltage Inductive Capacitance Ignition Probes Diagnostic-tool Accessories

Absolutely amazed at how good the fit and finish were on something like this that only cost $13. It worked perfectly with my JYETech pocket oscilloscope to help diagnose misfires on a couple vehicles. I was very pleasantly surprised at how easily it would grab a good signal without fussing with the setup. Still can't believe it's only $13. The 8-foot length was nice as well; easy to lay it wherever you need it to go. Would not hesitate to recommend this to anyone, professional or hobbyist. For the price you could get 4 to use on multiple input scopes and ready 4 cylinders at once and it won't break the bank.

Dose just stated work grate

Long grd lead, makes grounding easier.

Excellent build quality and great signal quality. Excellent value at a great price. The signal is very good and I don't know why I have already bought one of these probes.

Used this on a 2005 GMC 6.0L gas engine. Worked great. I was able to compare the ignition pulse of all the spark plugs and quickly determine that I had an ignition problem, not a fuel injection problem. Some of the pulses looked different from the others and those were the cylinders with bad spark plug wires. Paid for itself in only one use!

Helped me figure out what was going on with customer's motorcycle ignitions systems. Takes the guesswork out and it helps tremendously when you can see the details of an ignition event. A great and affordable piece of HT interface for your oscilloscope.Edited to add: Finding even more uses for this device. Checked the waveforms of my pickup truck's HV wires and saw some strange things, so I pulled the plugs out and they were badly worn out. The waveform is inverted from what you normally see in pictures on the internet, so once you realize that, no problem. I use this item with a little pocket scope and that makes it amazingly portable and easy to use.

I use this a lot on my scope. Give good wave forms works every time.Bad point only one realy the negative lead is to short. But so far all of the negative leads on these styles is the same just not long enough to use and sometimes it's hard to find a ground on the vehicle's.

Better quality than the original
