"You sense your mark..."

Was kinda intrigued to see this feature implemented. But, far as I can tell, it only triggers when you're within view of said mark? It's kinda a useless thing if you're only informed of proximity when you can already see it.

I'm supposing it'd be a bit much to expect it to trigger zone-wide. But, some improvement here would be appreciated.

I don't know, I go past targets constantly 'cause they blend in to the environment for me and stuff. My eyesight is terrible. Being told I'm looking right at it is more helpful than not telling me at all.
