A hand-mountable adaptive bar code scanner includes a scanner for generating a light beam directed toward a target, the light beam sweeping the symbol to be read. The scanner further includes a photodetector for receiving reflected light from such symbol, and circuitry to determine whether the signal received is sufficiently distinct to determine that a valid symbol has been scanned, and signal processing circuitry having adjustable gain, bandwidth, and digitizer threshold characteristics for processing such signals.
