bbTalkin is a bluetooth-enabled communication system reaching out up to 1 km.
BbTALKIN is an evolutionary Bluetooth Waterproof Communication Device which eliminates push to talk communication! It uses long-range bluetooth technology that allows people to communicate clearly with each other on the water. This system has bridged the gap between athlete and coach. This technology enhances the learning curve two fold.
The coach and athlete (student) are now directly connected being able to communicate instant instruction and feedback. The athlete’s progression and development is rapidly expedited with this communication capability. Can be used for all levels of training whether advanced (Pro), intermediate or beginner. The coach is able to relay feedback to the student immediately while on the water.
ceecoach is a bluetooth-based communication system made for up to 5 clients and 1 instructor.
