Despite washing the QOC sticks on a regular basis, they still have a bit of an odor. At a recent event, someone asked for one which didn't smell...sure, that will be $40, please.
Gord, I tried neck lanyards for the AR events I have supported. Granted, the events are longer than orienteering events, but they were just so gross to deal with after. Also, the metal hook rusts pretty quickly.
The system QOC uses is quite good for inventory purposes, as well as cleaning the cards with some regularity. I started washing because the smelly dried straps would trigger my asthma.
We still lose 1-2 each year even with the leashes because, well, people.
The leashes are made with mini cord locks from oregon cord lock, as well as braided (not twisted) #18 mason line, the brighter the color, the better.
