The AMA  BaquaPak makes it simple to get into the water.  No cases to open, no buttons to push, just plug in the headset, the red light flashes on, and your transmitter is ‘ON’ and ready for you to teach.  Only AMA’s patented ‘Positive ON’ connection system prevents the transmitter from accidentally being turned ‘ON’ (thus draining your battery) while being stored or handled.  To recharge the transmitter pack just connect the charger and plug it in!  You never have to open the waterproof case and risk water damage.  Additional headsets are available and recommended (due to the harsh environment of the pool) so you always have a back-up.  The BaquaPak System includes receiver, waterproofed transmitter and headset, recharger and BaquaPak (recharger not pictured).  Transmitter/Receiver brands include Fitness Audio Brand V-Series VHF mic systems.  Warranty 90 days on all parts.
