I purchased this meter approximately six years ago.. It does have some nice features but all to often, I have to push buttons more than once to get it to change a function. I returned one meter like this, one manufactured by the original manufacturer and one distributed by ExTech. All did the same issue.
There is no option to turn off the audio and make it "stick," you have to push several buttons at one time every time you turn it on, which is inconvenient. Thee battery life is shorter than the manual says.
Also, although there is an option to measure the individual axis of the EMF, X, Y, or Z, I could never find out from ExTech how to correctly correlate the axes with the actual direction they are coming from, (The meter appears to use the 3-D Cartesian coordinate system.) I escalated this as high as I could with ExTech and never was able to obtain an answer. Determining the direction of the source of EMF is vital in many cases, otherwise you have to guess using proximity using the omnidirectional antenna or all axes and never really know the direction of the source.
