There are two things I like about this. One, it's got just what you need to treat the injury anglers are most likely to inflict upon themselves or others. Two, this kit is small, flat, takes up hardly any room in a vest pocket or tackle bag, and comes in a zip-seal bag to help keep it dry. There's always a full first aid kit on my boat or raft, but I've already jammed one of Dr. Fishhook's kits in my fly chest pack and wader pocket. This is one of those items that goes in the "always good to have" category.
