Abstract: A disc sports device for attachment to a throwing disc having a circular housing, having a first side opposite a second side connected by a sidewall therebetween, forming a cavity having a printed circuit board assembly within, and a midline axis passing through the center of the first side, the center of the PCBA, and the center of the second side. The PCBA has a processor, a memory, a first accelerometer centered on the midline axis, a second accelerometer offset from the first accelerometer, a GPS module, a magnetometer, a gyroscope, and at least one wireless communication module, and a battery. The disc sports device has a connecting ring having a first connector side opposite a second connector side and a central opening therebetween, the first connector side having a disc connector and the second connector side having a housing connector detachably connected to the housing.
