Hey guys im looking for a good cheaper meter that i can take with me and check swr in my vehicles, cuz i dont like to take my dosey meter out. looking at spending no more than $30.00 Are the diesel and astaic brands that are at the truck stop very good, or just junk? Are the Ratshack meters decent? I know im not going to get the best meter for this money, but would like to get something decent. Thanks guys.
