The HF Little Fish throwbag is small. You would expect it to be given that it contains only 9m of 7.5mm floating rope. This puts it in the position of being longer than a bought rescue tape but shorter than most throw bags currently on the market.
Many years ago PFDs were produced with rear pockets to accommodate a throw bag. Many of those original bags were a flat envelope type and were pretty compact meaning they would fit in the PFD easily. Unfortunately they didn’t throw that well compared to cylindrical bags, had relatively short lengths of thin rope and repacking could be a nightmare. That said it was better to have one than not at all.
A pin kit is the collection of equipment that you carry to aid in a whitewater rescue that may or may not involve a pinned kayak or canoe. Within my paddling group there will be several variations of this kit, it is important that the group is not reliant on one persons kit as it may be that person or that persons boat that is in need of assistance.
The areas in which you paddle may also dictate the type and amount of kit you carry.
My current pin/rescue kit is as follows and includes the throw bags that I would normally carry in my boat or on my person.
The HF Swifty Belt is designed so that you are able to carry your throw line with you at all times. It is designed around the same belt system that you see on all rescue PFDs. The buckle is exactly the same and ensures that the system is quick release.
