Will this detect a clippard miniature valve coil? or just large ones? i have no idea what magnetic field detection range: 63h, 98h, 401h, 810h is.

It should pick up clippards. However, the light that indicates a field is not very bright. I use it to check on the valves for my irrigation system. They are 24AC and not very powerful.

Can this tool be used for magnetic field detection on watches?

I'm not exactally sure what you are asking. It will detect a magnetic field that might interfere with some watches. If that is not what you are asking please be more specific.

Will this detect a neodymium magnetic field?

Of course, this tester will detect. It starts sensing not so strong magnet like neodymium one in the distance of ~15 cm.

Can it detect GPS cases that use magnets under cars

Thank you so much for your interest in our products. The MD10 will detect magnetic fields if they are located in the available ranges of the unit (63, 98, 401, 810 Henry units). Also, it will have to be found in a short span of the source.
