The new LCD type displays today are very bright! The 2.4 GHz frequency counter version has an 8 unit display over your 6 unit display but ironically seem to use the same IC chip. I think you have been misled as this unit actually only goes up to 60MHz. The 8 unit display goes up to 2.4GHz! The pictures shown are for that type not yours. Dang Chinese.
Yes, I later was able to switch through the hi / low frequency menu. It apparently does .1 to 10 MHz (almost) on low, and up to 60 MHz on high. On high setting, I can still get down to a solid 455KHz for most AM IF tuning and up to the 10.7 I need for FM IF. It will also do the AM/SW bands on antique radios for RF tuning testing and dial setting. But for $20, it is a pretty stable device. To be honest, when I bought this one a few years back, I did not expect it to be anywhere near this accurate. I will be upgrading to the newer one though because it uses more digits.
