After arrow capacity, this is probably the leading question bowhunters have when considering a new quiver. It’s your choice, but here are the relevant factors pertaining to each type. Fixed-position quivers are generally going to be sturdier when mounted on the bow than detachables. That might be important if you tend to be rough with your bows, or if you’re stalking through heavy cover. Fixed quivers tend to be quieter when shooting because they aren’t made to be removed. But that was more evident 20 years ago than it is today. There are some seriously quiet detachables made today. With fixed-position quivers, you need to get used to having that weight on the bow while shooting. If you practice all year without a quiver on, and then attach one the day before hunting season, the weight change will be abrupt. Detachables are generally associated with tree stand and ground blind hunting, because those bowhunters get to a spot and then don’t move. You can take your quiver off the bow, and still have arrows within quick reach.
