A method for using the multifunctional navigation mark according to any one of claims 1 to 5, characterized in that: It includes the following steps: S1. placing the navigation mark in a preset water area; S2, sending a signal to the communication module in the navigation mark, so that the processor module in the navigation mark controls the lifting tube (2) to descend, so that the probe mechanism (3) extends out of the tail cylinder (500); S3, the water sensing device and underwater sensing device of the navigation mark transmit the collected data to the processor module for storage; S4. The ground platform sends a signal to the communication module of the navigation mark, and the processor module sends the data stored in the processor module back to the ground platform through the communication module.

7. The method for using the multifunctional navigation mark according to claim 6, characterized in that: When the navigation mark is recovered, a signal is sent to the communication module in the navigation mark, and the processor module in the navigation mark controls the lifting tube (2) to rise, so that the probe mechanism (3) is retracted into the tail cylinder (500).
