The MicroP25RX was Todd’s first attempt at a completely self contained portable scanner. It was superseded by the Nano. The final Bluetail scanner was the Eagle, a small self contained hand held scanner about the size of a pack of cigarettes. As near as I have been able to determine, there was only three Eagle prototypes produced, making it the rarest of the Bluetail line. There is an ongoing series on the forum of a base/mobile self-contained scanner I have dubbed the Eagle II. I am using a Nano as the basis for this build, but it could also be done using a Micro
