I used an A-rated one in beta (24 km range), now a C-rated one (18 km range). There is absolutely nothing revealed about asteroids 18 km, let alone 24 km away. In both cases, I start seeing a vague glow about 6 kilometers out, but the actual glow-strength is only revealed once I get to a range of about 2 km.
This isn't a huge complaint, even a fast ship isn't fast enough for this to really make a difference, because I can always just fire another scan... but if you're gonna have the full E-A rated selection of modules (with vastly differing prices and power draw), they might as well perform differently.
