1 H-900 FM Transmitter Wireless Good Quality Earphones Running Jogging Driving Sweatproof 1 H907 Bone Conduction Headset

Function:
(1) Multichannel Function
Both the headset and walkie talkie can be used simultaneously on 7 different frequency channels enabling up to 7 coaches on the same pool deck to communicate to 7 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 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.
(5)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.
(6)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!
