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. **Q: Can this tool be used for magnetic field detection on watches?** A: 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. **Q: Will this detect a neodymium magnetic field?** A: Of course, this tester will detect. It starts sensing not so strong magnet like neodymium one in the distance of ~15 cm. **Q: Can it detect GPS cases that use magnets under cars** A: 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. ## Frequently Bought Together - Extech MD10 Non-Contact Magnet Detector with Built-in Flashlight - Solenoid Magnet, Solenoid Valve Magnet Tool #TLMKC, Solenoid Valve Troubleshooting Magnet Tool 18mm, Fits Most Industry Valves, 1 Pcs - Rotation Tester and AC Detector for Circulating Pumps etc --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/10170184-md10-non-contact-magnet-detector-pen-with-built-in-flashlight](https://www.desertcart.ro/products/10170184-md10-non-contact-magnet-detector-pen-with-built-in-flashlight) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-07-21*
