Hi,
Looking for rowboat system for cox to use wireless headset (bluetooth?) to bluetooth speakers.

 

• They're not allowed cellphones in case coaches communicate
• Trouble is they want it cheap and I know where that leads....

They use a battery in the boat but a wireless charging system would be ideal and obviously any delay would mean they would be out of time.
I thought ipod touch with headset and bathroom bluetooth speakers.

Any ideas or thoughts are appreciated.
