Whistle FIT is water-resistant (rated IPX7).
This means the device is designed to go anywhere with your pet in 1 meter (about 3.3 feet) of static water for up to 30 minutes. We recommend drying the device regularly, especially after swimming, to keep it from rusting. Do not attempt to charge a wet Whistle device!
Keep in mind, water resistance is not a permanent condition and might decrease as a result of normal wear.
