Mighty GPS

Weatherproof GPS Receiver



This is a “mini” external GPS receiver with Mac drivers available, which utilizes a bulkhead (through-hole) mounting design for applications that require a more permanent weatherproof mounting solution. The built-in GPS receiver is self-contained with the latest “20” channel SiRF Star III high performance GPS chipset for accurate positioning and an active patch antenna.

The extended 15’ data cable allows for easy routing to your laptop behind headliners and side panels and terminates to a custom PS/2 connector for interfacing with one of the available cable kits (USB/RS232). This is perfect for boat owners and for fishing enthusiasts. This can also be used in a wide variety of applications including being mounted on police and fire trucks, utility/commercial vehicles, boats and aircraft.
