- Advanced (+1%) cost: 1 point
- Gifted (+2%) cost: 2 points
- Master (+4%) cost: 3 points
- The % here is not an accurate reflection of the in-game mechanic. It is actually +1 parsec to sensor range instead of 1% bonus to the default sensor range.
- Note that there is a hard-coded limit to sensor range of 15 parsecs, meaning that these bonuses will be "lost" if you reach that limit (such as by building Eyes of the Universe).
