Helpful High-Quality H-903 Waterproof Wireless Swim Portable Light Comfortable Bone Conduction Earphones

Bone conduction Swimming/aqua-sport training equipment

Introduction

We know how difficult it can be to communicate with swimmers during training. High volume and poor acoustics in swimming pools force coaches to scream to be heard by the swimmers, and while swimmer, they don’t hear you at all. Coaches haste that they waste too much time in screaming but get poor communication effect, even bring negative feeling between coach and swimmers.

With our gadget,you can solve all these easily.

It is an outstanding tool for training sessions and swimming school or aquatic sports communication. The coach can motivate and encourage the athletes to greater commitment and give them continuous technical corrections from the poolside. This allows the swimmer to get real time hints about stroke rate, lap times, feedback during turns and rhythm or breathing cycles changes.

Application

Swimming, open water swimmming, surfing,underwater exploration,underwater ballet,water polo,sailing...

How to use it?

Our system contains a transmitter and some bone conduction receivers. Transmitter is for the coach, while receiver is for the swimmer.

The receiver have 7 channels with different frequency. Just need to set your transmitter and your receiver at same channel. Then speak to the transmitter, the swimmer will hear the coach’s instruction through the receiver even if the swimmer’s head is underwater.

For more details, please contact us.

We have 6 model groups for your selection

H902+H900B: signal distance is 120-200M, 7 channels.

H903J+H900B: signal distance is 120-200M, 7 channels. With volume button on headset

H903MJ+H900B:signal distance is 120-200M, 7 channels. With mp3 player function on headset

H905A+H900A: signal distance 1000M,with noise cancelling,7channels

H906A+H900B: 1000M,with magnetic-charging+ intelligent broadcat+save electricity,7channels

H907J+H900A: same as H905A+H900A,with with magnetic-charging+ intelligent broadcat+save electricity,7channels

Function:

(1)multi Channel function

Both the headset and walkie talkie can be used simultaneously on different frequency channels enabling differentl coaches on the same pool deck to communicate to 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)Technique Training
Having the ability to tell the swimmer to get their elbow up higher, no a bit more, more, that it' - helping the swimmer with learning more about special awareness which is very important. What the swimmers thinks is right is allot of the time not correct and with the Device you can give them advice they need while doing the exercise.
(4)Stroke Count, Stroke Rate and Temp Training
A great option is to to give feedback one stroke rate or tempo while the swimmer is doing a swim set. They learn just what stroke they are doing as they are swim it. Have a team of swimmers using the Device, you can have multiple swimmers so you can do ream work outs. Have a whole team working on the same stroke rate via a mp3 file. You can change the tempo mid length or at the end of each lap/set via a mp3 player or cell phone.

What’s bone conduction?(science reason)

Sound are decoded and converted into vibration on facial bone! directly received by cochlea----bypass eardrum. No electric-Magnetic wave.

Advantage of bone conduction tech：

1,Let ear absolutely free at the same time, you can still enjoy your normal conversation

and listening to the surrounded sounds without

removing the bone conduction headset

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

How to use this swimming teaching systerm device?

(1),about channel and how to use

Walkie talkie is for coach, headset is for swimmer.

The walkie talkie has 7 channels (we marked LED as red, yellow and blue) to enable 7 coaches to teach the same group or teach 7 different group in the same pool. And one channel can speak to many swimmers, no limit.

Just need to adjust the walkie talkie and headset onto the same LED color. When you need to change channel, remember to remind your swimmer to turn their headset to right LED color before you change your channel.

Example as below

(a)One coach teaches 7 different swimmers groups----you need to use 7 walkie talkies at the same time.

For example

Group A: blue channel --(Pls turn both walkie talkie 1 and group A's headsets into blue channel)

Group B: red channel     (Pls turn both walkie talkie 2 and group B's headsets into red channel)

Group C: yellow channel (Pls turn both walkie talkie 3 and group C's headsets into yellow channel)

when you speak to group A, pls keep group B&C's walkie talkies on work, don't closed it.

For H900B walkie talkie:Pls use 3 walkie talkies H900B, don't try to use one walkie talkieH900B to change the channels constantly. Or there will be noise if the group is not on active channel.

For H900A walkie talkie,only one walkie talkie is ok. Because they have de-noise design. When the channel is not on active channel, there won't be any noise in your ear)

(b) 3 coaches teach 3 different swimmer groups (each coach needs one walkie talkie)

Coach A teaches Group A: blue channel   (Pls turn coach A's walkie talkie  and group A's headsets into blue channel)

Coach B teaches Group B: red channel    (Pls turn coach B's walkie talkie  and group B's headsets into red channel)

Coach C teaches Group C: yellow channel (Pls turn coach C's walkie talkie  and group C's headsets into yellow channel)

Much the same point applies to 2groups or one group.

(2)The signal effective distance

From the walkie talkie to the headset: the straight distance is about 120M ,and can be boosted up to more than 150 mts with an optional three way microphone (sold separately).For the headset, it can be used in 3M depth underwater.

So, the coach can teach the swimmer far away, also can stand on a upstairs place to look down them
