Should anyone have a set of Martin electronic bow scales set up on a draw board or hanging vertically to test draw weight /cam timing, check your O ring! Especially if you've had it for a while.
Here's mine after failure. This was permanently fixed to a D shackle and in turn to a fully closed eye bolt (in 50 cm wooden support beam).
Unfortunately this failed when I had the bow at full draw, derailing the string off the cams. Nearly **** myself when it happened. Getting the bow checked out Tuesday.
