It was a great tracker, the signals were transmitted relying on the satellite, and it had a complex radio frequency signal that could cover up to two kilometers.
However, this was on land, and the Inuit man jumped into the lake after that. When he jumped into the water, the signal on the tablet became bad instantly.
Li Du quickly asked, "Is the tracker waterproof?"
Making an 'OK' sign with his hand, Young Markelov said, "The signal would be worse in the water, but rest assured, it is waterproof."
Indeed, the signal reflected on the computer could be clearly visible although it was a little weaker.
They would not dive into the water because the boy from before had jumped in and disappeared, and Li Du was always cautious of the lake.
Young Markelov had an idea that they could track from the surface of the lake in the kayak. The lake was not more than 500 meters deep anyway, still within range of the tracker.
