—Why the the headset and the walkie talkie help both swimming coaches and students a lot? 

 To the coach:

It makes the swimming training much easir becase the coach can directly teach and guide their trainees by just talking to walkie talkie, most importantly, the coach can guide many trainees at the same time, there is no maximum limit.

It  makes the training process far more efficient.

To the student:

During the swimming training, the trainees/students can hear what the coach said very clearly underwater through bone conduction. So They can correct  their wrong action very quickly and learn fast. 

They don't have to stop swimming and come up from the pool to  get their coaches' guide. 

——How could the coach be heard by their students?

There are 7 channels. Both of the coach and the student can switch channels by short pressing the button on their gadget. When they are operating on the same channel, then the coach can be heard.

——How could the coach and the students know they are on the same chanel?

If they are not on the same channel, the student will hear a lot of noise. Similarly, the student can hear the coach very clearly without noise if they are on the same channel.
