2,Hearing aid and protection, ok for people with hearing loss and impairment, and help prevent hearing deduction/loss

3,Even in high noise condition, you can hear the clear sounds by the use of ear plugs for the protection,even if you ear is full of water. Give swimmer clear instruction

4,perfectly used in the water or special work environment

(1)multi Channel function

Both the headset and walkie talkie can be used simultaneously on 3 different frequency channels enabling up to 3 coaches on the same pool deck to communicate to 3 different groups

(2)Real time feedback

Real time instruction from the coach to the swimmer has always been problematic. The swimmer could only be rectified with stroke errors after the fact when the swimmer has finished his lap. Now the coach can react immediately on wrong technique or body position allowing the swimmer to respond and cause muscle memory to set in at an early stage.

(3)Range

The range can go up to 150m and works best up to 75m so it is perfect for any 50m swimming pool. It works best with line of sight and works up to 3M under water.

(4) MP3
Want to jazz up long hard training sessions? Simply plug in your iPhone or mp3 player and give your swim team the ability to swim to music together!

1,The walkie talkie is for the coach, while the bone conduction headset is for the trainees

2, There are 3 colors of LED light in both walkie talkie and headset.(red,yellow and blue), when using them, pls do adjust the light to the same color in walkie talkie and headset. Otherwise, the headset can't receive the singal from walkie talkie

3,One walkie talkie can speak to 15pcs headset at most at the same time. The coach can devide the trainees into 3 groups. Team work!(one coach instructs 3 groups or 3 coaches instruct the same team at the same time!)

The maximum is 5 in each group, so maximum of 3 groups=15 persons.
