Maxton X100 Handheld Frequency Counter. Condition is "Used". Lightly used, 0.3 to 50 MHz and 50 to 2800 MHz. No antenna, no charger, but it takes a standard 12V, center pin is +. Any antenna including a wire will work. I see these new from China for .99. At this level of quality, it is not extremely sensitive. I have to hold an HT just about three inches away to get a freq count. Shipped with USPS First Class.
