EXPLORER 721 VHF
Explorer 721 VHF: Second Station Capable Radio
We've designed the 721 model with ease of use in mind. The super large display ensures a host of important information is clearly viewable. Keep track of barometric pressure, fishing conditions, and with four lines of text, you can easily view DSC messages, boat position, time and channel name. This model also features the option of a second station handset (the 701). Ideal for fly-bridge, sailboat cockpit or anywhere a second VHF station
is useful.
Weather Watch / Fish Forecaster
Unique to Northstar's Explorer 721 is barometric weather forecasting. Barometric pressure is presented using highly accurate digital graph technology so you can see the current reading and trends to assist in determining rapid changes in air pressure. We've even included icons to display predicted weather conditions.
Going fishing? Check the 4-level "Happy Fish" icon on the LCD to determine the likelihood of good fishing conditions. No more excuses for coming home empty handed!
Track Your Buddy
Track-Your-Buddy is for safety, teamwork, convenience or just for fun.
This great feature allows you to combine your Explorer 721's DSC position polling with Track-Your-Buddy enabled Chartplotter or Combo units to show the location of up to three boating friends on the chart display.
It's easy to setup: You need a Northstar Explorer 721, the MMSI number of your buddies' DSC enabled VHF radio, and a Northstar Track-Your-Buddy capable unit. The Explorer 721 will regularly poll your buddies' position which will then be updated on the Northstar display.
A great function for fleet voyages or any application where knowing the location of your boating partner is important.
