Thought I would pass this along for everyone here. Hopefully this will save some folks here alot of money. I'm seeing a large number of crossbows coming in with ruined cables. Some had cable slides and some do not. There are now cable slides for several models that didn't come with them. If you are missing your cable slide get it replaced as soon as possible. Shooting without a cable slide will damage your cables and they will need replaced.
Also check them for cracks, seperations and breakage.
