Monitoring system for an archery bow, monitoring devices, and methods for same

A method for diagnosing an abnormality of an archery bow, the method comprising:

• detecting, by one or more controllers, an operating condition of the archery bow from at least one onboard monitoring device of the archery bow;
• comparing, by the one or more controllers, the operating condition to a threshold operating condition;
• identifying, by the one or more controllers, an abnormal condition based on the comparing of the operating condition to the threshold operating condition;
• and
• presenting, by the one or more controllers, the abnormal condition to a user, wherein:
• detecting the operating condition comprises detecting, by the one or more controllers, a rotational velocity of a cam assembly from an angular position sensor of the cam assembly when a bow cord is released from a firing position;
• and
• identifying the abnormal condition comprises identifying, by the one or more controllers, a dry fire event when the rotational velocity exceeds a threshold dry fire rotational velocity value.
