Review: Better than expected - Works better than I expected it to for checking DC hydraulic solenoid valves. It is a little tight getting the cap off to swap batteries, but nothing you can't handle with a little flathead screwdriver. The light on this is useless though, but that's not what you're buying this for. Review: It Really Detects Magnetism - Bought it on a whim. It really works. Still experimenting with it, but it is a real tool. It will not sense magnetic field from low to moderate DC current flow in a single wire. It will not sense magnetic field in a refrigerator magnet. See Halbach Array on Wikipedia. ## Features - Contactless detector quickly determines the presence of magnetic fields (AC/DC/Permanent) - Test solenoid valves in pneumatic/hydraulic control equipment and audio speaker coils - Built-in self-test magnet and LED flashlight - Low battery indicator - 2 x AAA batteries included ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08BTQ4YSZ | | Batteries | 2 AAA batteries required.
