This is a very interesting little device. I purchased it to use with my HAM radios, in setting up the antenna and check the power output when working on the sets. I find it has a lot of other functions that are up my line of interests, for example my daughter and niece are ghost hunters, this looks like a nice addition to their set of electronic monitors for that hobby in that it is said that EMF changes when spirits are near and this has a nice EMF function as well as changes in magnetic fields are often detected when spirits are near as can be seen on the almost comic television shows about ghost hunters on the once interesting travel channel that appears to be the all ghost all the time network now days. Came very quickly. It appears that the unit I have perhaps has a flaw in the software, when I turn the screen brightness down it makes the Electronic field hundreds of times more sensitive, perhaps it is putting out it's own electronic filed when the screen gets dimmer I don't know but it makes it a better ghost detector that way I guess.

Product is as described by seller. The meter is useful to measure electromagnetic fields and radio frequencies. The display is bright and shows all parameters in one screen including the alert levels as set by manufacturer or user. It uses 3 AAA batteries. The batteries generally are not sent with the product, as I assume due to aircraft cargo restrictions.
