GOST Nav-Tracker 1.0

This is the most basic version in the Nav-Tracker family of tracking systems and is designed for customers who are primarily interested in tracking.

This unit also has an optional water resistant latching push button that can be used as either a panic button or an arm/disarm button, see below for more info.

This unit meets insurance requirements for tracking and was originally created at the request of the insurance companies as a low cost GPS tracking system for their customers. Many insurance companies offer discounts for customers who install ANY GOST NAV-TRACKER system on their vessel. The GOST NAV-TRACKER 1.0 uses the same technology and 5th Generation Website as other GOST NAV-TRACKER versions.

GNT-1.0-60 includes the antenna and 60ft cable
GNT-1.0-90 includes the antenna and a 90ft cable

GOST Water Resistant Latching Push Button

Boat GPS Tracking SystemsThe GNT-1.0-Push-Button is an IP67 Rated water resistant latching push button (push on – push off). The push button can be used both as a covert geo-fence arm/disarm button and/or a panic button. When used as an arm/disarm button it will control the geo-fence on board the vessel. When used as a panic button, the GOST Nav-Tracker will send ‘in alarm’ messages with the vessels name, latitude, longitude, speed & heading, and will continue to do so at whatever interval is selected on the website (2 to 30 min) until the user presses it again, at which time it will send the same information with the message ‘alarm cleared’. The messages will be sent to the website and to any designated message recipients as an email or text message. This feature is very useful on jet skis or other small watercraft when users run out of fuel, get lost, get into trouble or cannot get the jet ski started after a spill.
