Bloons TD 4Edit
It allows nearby towers to detect Camo Bloons. Note that Monkey Aces will always be able to pop Camo Bloons, even accidentally.
Bloons TD 5Edit
This allows the Monkey Ace to hit Camo Bloons. Even though it does not aim for a target, it still needs this to pop Camo Bloons. Otherwise darts and explosives from this will not pop the Camo Bloons. Spectre and Neva-Miss Targeting will target Camo Bloons but will not pop them without Spy Plane.
Bloons TD 6Edit
Similarly, this also allows the Monkey Ace to hit Camo Bloons. Likewise to previous versions, it allows the Monkey Ace to pop target and pop camo bloons. All upgrades require Spy Plane before they can pop camo bloons, besides Spy Plane's subsequent upgrades Bomber Ace, Ground Zero, and Tsar Bomba.
- In BTD5, this upgrade does not allow camo detection for all towers.
- The Spy Plane in BTD4 looks similar the real-life SB2C Helldiver.
- In BTD5, without this upgrade, darts shot from the Monkey Ace will still be fired, but won't pop the Camo Bloons they make contact with, and will simply pass harmlessly over them.
