I just purchased a Carter Attraction S release used for $50, it seems to be working, however I was told that I can adjust the trigger release and/or tension release. I can't seem to find any info online regarding how to do this. I can see several holes for allen wrenches but have no clue how to adjust. Any information anyone could provide would be greatly appreciated. I'm trying to keep the trigger release but lower the release to make it more sensitive. Thank you for your help in advance.
