DNA Scanner

The DNA Scanner is an item in Plants vs. Zombies: The Cure. It is obtained in The Virus, and has a range of 9 tiles. It cannot be upgraded.

Appearance
The DNA scanner is an iPhone-like device with a triangular attachment on the end and a handle. When it does not find any new plant DNA, its screen is black, and when it does, its screen is green and displays the name of the plant in black.

Behaviour
When equipped, the DNA Scanner's screen is black and it will not do anything. When it senses plant DNA within its range, it will beep and its screen will be green. It will display the name of the plant in black. It stays this way, beeping and adding more plant names as it detects more plants, until you plug it in a Plant Incubator.

Strategy
Always carry this item in your off-hand, as it is the only way to unlock most plants. When it beeps and you are not doing anything, head to the nearest Plant Incubator. The plants might give you an edge in battle, and if you are sure your defenses can hold, do this during battle, too.

Trivia

 * It is the first item that GravityWave made.
