I have noticed that when practicing in the yard that my rest tends to fall on its own. It is like their is no resistance to hold it up in place. It just started doing this recently. I have read that under the rest their is a screw for the sensitivity and it may need to be adjusted. Sometimes the rest will hold just fine like it is supposed to but sometime it drops away. Does anyone know anything about this by chance? Any help is greatly appreciated. Thank you in advance.
