It should either by given the additional ability to grant you the keen-scout perk for free, or it should keep radar up while aimed with all of your weapons (except maybe snipers), not just your primary. Minatosensei4's idea: [quote]It needs the ability to keep radar up, regardless of the weapon type, and have enhanced radar like Keen Scout and Relentless Tracker. Perhaps the ability to highlight enemies with a red outline when ADS like the Signal MS5 Omolon sight.[/quote]
