The GP1650F's sensitive GPS receiver gives accurate boat speed, heading and position information. And, if that isn't enough, the unit features a dual-frequency (50/200 kHz) 600 Watt (RMS) 2400 P-P echo sounders that detect fish and provide detailed bottom information.
The GP1650F accepts either Furuno or Navionics® mini-chart cards.
