Meat tenderizer for jellyfish stings (added to my very good first aid kit)
Small bottle of sunblock (not emergency but really helps)
Phone charger cable since I have USB port in console
Package of handy wipes for various needs
I have a small backpack that I carry with sunblock, small first aid kit, pliers with side cutter (when you are not fishing barbless), antiseptic cream, extra knife, waterproof ID, alcohol wipes.I carry this with me, because if you fish with somebody else, you may not have access to these things.. My wife was a nurse, so we err on the side of caution.
