Hantek HT25COP Ignition Waveform of Automobile Engine Coil-on-Plug and Signal Probe, can be Works with Normally oscillscope

It does a good job. Have used it several times and it produces a nice clean signal on our scope.

Don't expect a nice fat'n juicy fire line. With this wand you get a relative reading. So far I've tested with a hantek handheld meter, and the hantek 8 channel scope, a little better on the scope but not as good as back probing the coil. It's great for quickly detecting a faulty coil or circuit. Is it worth the hassle of back probing a coil, digging out a scope, finding a decent place for your laptop so doesn't slide into the radiator fan: YES

I use this product to help me with my 2005 Ford Explorer ignition coils and it worked. Worked perfect as it was intended. Thank you for the great quality.

Works only according to the amount of shielding on the coil. As I work on a wide variety of cars it's still a worthwhile addition to my kit.

Your scope should be able to go to 5mv/div or so as pick up the signal from shielded coils. My really cool dual trace tablet scope only went to 50mv/div and did not help but with my Owon scope meter, and my Rigol DHO804 this probe works very well.

I used it for automotive diagnosis on secondary high voltage at plug wires.

On the COP coils you get a nice clean constant waveform. For the money it can't be beat.

Results subject to interpretation, works well.Don't waste a battery because the light is a total joke
