For best results, ensure that this device is tied off to a tag line, surface marker buoy, or anchor line on the surface where it is not obstructed by the hull of the boat and has a clear line of sight to divers with compatible devices.

If you are towing the device, ensure that it is affixed to an appropriate surface marker buoy and flag so that it is visible to vessels.

Submerging the device for extended periods of time can degrade device performance and/or damage the device.
