Throw bag

A throw bag is standard rescue equipment for kayaking and other outdoor river recreational activities.

A throw bag is used to rescue someone who is swimming down a river after capsizing their kayak or canoe[1], but can also be used for gear retrieval and for climbing during portages.

Have parties on both sides of a river that is smaller than the length of the line.

Throw a bag from one side of the river to the other with both parties holding an end.

Using angles, position them, the gear, and lower them down for rescue with either a pin kit or basic retrieval.
