Kit includes a Ringboom, a SnapAway Linkage and a mini carabiner (lure line not included).
Notes
There is a snap swivel for your lure line, and an O-ring for it if it needs one.
The SnapAway clip is attached to the linkage, so it's not lost if a line hanger goes missing.
The cable end loops are double-crimped.
A long lure line streams back like a kite tail, but a short one is less likely to get tangled around either the main flying line or an aerobatic bird (Murphy's Law).
