Does the job, Easy and for good price.

Worked as advertised, variable beep relates to proximity. I didn't find it too sensitive as other people have commented on reviews. Maybe the product has been updated, but it does differentiate between sources an inch apart. On fuse box, tested those double contact fuses and could find one where one of the contacts had no current and the other did.

Pros
