you need to attatch a line to the hole in the end cap to form an exterior loop then snap a caribeener into the loop so you have the beener hanging from the loop on the end of the poon
now take your dart line and tape it tight to the shaft to hold the dart
now the dart line goes thru the beener and serves as your dart line and saftey line in case you need to throw this way you only have one line to deal with.
The carabineer on the end will fit right into the rod holder so your poon is ready to go on a moments notice with all the line attachted and the saftey /mainline intact
