What is the maximum immersion depth of the TruDefender?

• A. 0.2 meters for 5 minutes
• B. 0.5 meters for 15 minutes
• C. 2 meters for 60 minutes
• D. 1 meter for 30 minutes

Answer: (D)

Immersion protection is about how water-resistant a device is, expressed as a depth for which it can be submerged for a certain time without water getting in. The TruDefender is rated to withstand immersion up to 1 meter for 30 minutes, which corresponds to the common IP67 standard. This means it can handle brief submersion in shallow water or exposure to rain and splashes during field use without compromising its electronics or readings. The other options describe conditions beyond what the device is guaranteed to withstand or are not the maximum rating it carries, so the stated maximum immersion depth and time is the correct choice.
