The Mastodon Bow Hanger was a hit for us. Being the first mobile solution to bow hangers that swiveled horizontally and vertically! The 2.0 now takes that up one more notch. As well as swiveling horizontally, you can now adjust the angle of your hanger. Using a PROVIDED allen key (with a storage slot) you have three points of adjustability. The allen key also works to tighten or loosen the bolts/nuts to desired tightness.
