Halo, i have a bit off-topic question for the forum, but i couldn't find assistance anywhere else... So i am from Ukraine and i am a big bear hunting fan. Me and my friends we all have this gps devices www.nav4all.com and they are very nice because we know where we during the chase. Nevertheless i have had this idea of of also being able to see my friends devices on the screen of my phone. Is it posible if speacking on theoretical level?
