I bought one of these a few week's ago with the idea of leaving it in the MH so as not to have to remember to pack my $350 "Amprobe" or "Fluke" when taking a trip and expecting to need a meter.
I have been pleasantly surprised by this $70.00 meter, while I wouldn't say it is as rugged ed as either of the other two meters it certainly seems as accurate or at least close enough for what I need in the field.
This is the cheapest of it's kind I've found in a retail enviorment, and at the moment at least I'd say is a good buy.
With reasonable care it should last quite a while and be quite usefull to anyone who knows how (or takes the time to learn) to use one.

I already have meters laying all over the place. I have an analog Simson, a couple of small meters from R.S., one even small enough to fit in my shirt pocket(actually smaller than a pack of smokes) leads and all. I even have a digital that also has a scope function from Sears.

One dedicated to my tool box, a couple in the Radio room and also two the MH.

But I do not own a clamp meter.

One of the reasons I posted about this meter is that it will do "D.C. Amps" as a clamp-around.
This is something you don't usually find in this price range.
Also something that most people who deal with RV electrical systems (and HAMS) would find most handy at one time or another (look at the spec's).
