There are also settings in the sensors.cfg file for whether or not the crew rating ("efficiency") changes the efficiency of the sensor in the crews' hands. Whatever you do, don't sneeze at the wrong moment, and turn a "0.1" into "0.01"...
- so you can have a "Competent" crew using their radar or sonar at full strength, like they are "Elite". They just can't "drop the boom" so well maybe... It would be nice to be able to at least tune that for each ship class, but oh well, it is complicated enough as it is already... lol
