Now the coach can talk to the swim in real time while they swim giving the swimmer and coach an ability unique ability to change technique as the swimmer is swimming. Before the swim coach had to wait until the swimmer had finished the end of the swim length or swim set. By this time the swimmer has already repeated countless incorrect swimming stokes. 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. 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.

But instead of sending them through your ear canal, it transforms them into sound vibrations and sends them, via the abutment and implant, through your skull. in this way the vibrations travel directly to your inner ear, bypassing any problems in your outer and/or middle ear even if you ear is full of water.
