Our family found a belly bag (Its black with reflective sewn into the front) that our unit fits into. It works out really great because there is a zippered pouch that runs the length of the bag for papers (All of our printed off cache sits with logs and info), there is a front zippered pocket (We store some pins in it that we leave at caches), 2 small side compartments and the regular front zippered larger pouch. We store our unit and bigger trinkets in there.
ANyway. Saw this thread and thought I would put in my 2 cents!
