    Accelerometer-only Apogee Loggers

    Hello! I'm currently making a bluetooth apogee/gforce logger using 2 accelerometers(1 watchdog in 16g mode, 1 high-accuracy that varies between 2-16g mode) and 1 gyroscope. I'm curious as to if there are any other apogee loggers which use only accelerometers, and if their accuracy is as good as...
