Do other hunters have to have Huntloc app to see their locations?

Yes, every hunter have to have installed and running Huntloc app on their smart phone. Huntloc app sends hunter location parameters to server. Where information will be downloaded and shown graphically on map. For information exchange and positioning it is necessary to activate mobile data and GPS connection. In same manner works dog tracker as well. In dog collar there are GPS and GSM components for positioning and location sharing to Huntloc server and hunters.
