Worked great.
I used it to check and see if i was getting a good spark from my coil pack on my outboard motor. It worked perfectly and was easy to operate and see the spark.

Mejorar saltos de corriente en la estructura.
Buena herramienta para diagnósticar los sistemas de encendido. Tiene solo un error en artículo, genera saltos de corriente que afecta al operador. De resto súper.

Works well
I use it to bench test ignition systems. It worked well even at 15mm gap [~45KV]. After several minutes of on continuously the clear guard deformed due to heat [remember arcs are 50000°]; it still WORKS!

Old homemade tester took a dump and always had to have two people to use, with this I've been able to test by myself at least so far
