FEATURES ArmAlarm gives real-time feedback on one of the most critical aspects of the golf swing...arm structure. Keeping your elbows close to each other throughout the swing pulls the rest of the swing together. Chicken wing? Flying elbow on backswing? Pulling your hands in at impact? If this is you, ArmAlarm is the answer. ArmAlarm beeps instantly when your elbows separate in your swing. Adjustable length tether and straps to accommodate all sizes and abilities. Includes WristAlarm that beeps if you flip or scoop. You can even use it on the course...until your buddies whine about how good it makes you!
