add beacons to your presto hud and it would be complete. It's easy just look for
HUD::AddTextLine(hudDyn, "<f1>Mines: <f2>" @ getItemCount("Mine"));
HUD::AddTextLine(hudDyn, "<f1> Grens: <f2>" @ getItemCount("Grenade"));
and add this at the bottom
HUD::AddTextLine(hudDyn, "<f1> Beacons: <f2>" @ getItemCount("Beacon"));
