$320.00 !!! They must be really proud of it judging by the price!! Ameritron makes one too and you'll save about $200. Has preset memories too.
They're not even in the same ballpark.
The Ameritron unit is a turns counter, nothing more, nothing less, is prone to inaccuracy by missed counts and I know one of the versions lost the presets if it lost power.
The Turbotuner 2 is a proper SWR detection screwdriver antenna controller with a park function, it also remembers which direction to move the antenna depending on the band change, and is controlled by using the radio's tune button. Unlike the Ameritron it can be mounted anywhere at all so can be hidden out of sight. You've got to find somewhere to put the Ameritron where you can reach it.
