We've just had an update from Ben Pokaia - Nomad Sportsfishing NZ - who has recently had a GPSMAP8015 and GSD26 Chirp unit installed on his boat. According to Ben "1k chirp is the best sounder I have used and seen" , A big call from arguably the best king fisherman in the country, but as you can see from the pictures below that's no exageration!
