A really tiny whistle... ...with a frightfully big sound! Never thought I'd see a whistle so miniscule, yet so profoundly loud! Just what I need when I'm dropped into the dark, dank myrtle glooms of a NW Tasmanian rainforest on a photographic expedition. This beautifully designed, precision constructed little trinket joins a retinue of other emergency comms devices for sorties into the wild: a GPS, Zoleo satcom and PLB. ___________________________________ My own lanyard attached to the whistle.
