Like the 'coil type' above, turn it on several feet away from the work, walk towards your tools or movement, then walk away before turning it off. I assume the 'pulse' unit works like a TV tube (soon to be another outdated term) auto degausser which is also limited in demagnitizing power. I am still amazed how quickly tools can become slightly magnitized and I am not sure how it occurs, seemingly from just using them. If watch parts were not so small and low in mass it would not be noticeable. An easy, effective and cheap demagnitizer can be found in any wall powered VHS tape eraser.

But it does provide a nice look. I never use the compass. But it does provide a nice look.

The compass in the lid is a nice touch - do you find you make much use of it for detecting magnetic fields? I love the look of that old coil demagnetizer.
