My son Aaron purchased the new Dragonfly 4.3 from Whitworths on Saturday for $369.00 including C-Map. The salesman told us how the new transducer was designed so it could be installed inside the hull. So The Dragonfly has now been fitted to the Kawasaki Ultra 310X with the transducer sikaflexed to the inside of the hull right at the front of the motor. Aaron took it out for 1.5 Hrs this morning and it worked like a charm. Was still reading the depth at full speed. I will try & include relevant photos of how aaron installed the unit.
