It works perfect to test industrial solenoid valves
Works as described for industrial solenoid valves. Lost it, buying a replacement.

Useful in plant diagnostics
I've just finished testing this.First off, I think it would be much nicer if there was a status LED to say that it's actually powered up, just because the battery could be dead and it would look the same.Others here are bothered by the momentary switch but that doesn't bother me and I like that it can't be left on. The flashlight, which is pretty good, is also a momentary switch.--- Everything I tested was at 24VDC ---Mine picks up MAC valves well, but doesn't see our SMC valves, like the SMC VQ4101 that we have a lot of here.Ice cube relays read well, but the tool has to be near the end with the coil so there's no dragging it across the top of a bank of relays in a panel. Fortunately it has the little flashlight to be able to look the relays over and identify the coil side.Contactors are a little sloppy, they read but trigger the tool from several inches which could lead to false alerts if several contractors are close together.Overall I think this tool is worth the asking price, not perfect, but it's usefulness is greater than the price so I'm doing 5 starsEdit: accidentally discovered the little cap that pulls off the back side and appears to do nothing has a magnet in it to verify the tool with!

great for checking electric trailer brakes.
I bought this to check the electric brakes on my camper. It works great. Pull the breakaway switch and look for the magnetic field on the brake drum. I couldn't be more easy.

Great tool!
Works great to find energized relays but unfortunately it can’t catch 5V relays.

Great for checking relays
The media could not be loaded. Bought this for automotive diagnostics and so far it works great for many things, relays, electric pumps, solenoid valves. Etc.
