Continuous Glucose Monitoring devices provide glucose concentration measurements in the subcutaneous tissue with limited accuracy and precision. The BHRT includes one or more conduits, one or more tension members, and buoyancy. The accelerometer is coupled to the equipment mounting surface and configured to sense accelerations of the waterfowl decoy body when propelled across the surface of water, and the microcontroller is coupled to the accelerometer and configured to calculate a distance traveled by the waterfowl decoy body when propelled across the surface of water. In addition, each engagement element may include a hook configured to engage a corresponding feature of a foot-receiving member.
