If you really rely on GPS for navigation and piloting,you need to have a robust backup plan for when your primary fails. Often the cause of the failure can take out back ups. You need to have one device you can count on when the chips are down. What is yours?
Here is mine, and why: GeoNav 4C
This device was a gift from the President of Navionics, and has stood the test of time. Here is why:
Bulletproof. You can drop it. You can stand on it. You can through it at an pirate, disable him, and then use it to navigate your escape. Totally waterproof of course.
Flexible power: It runs for days on 4 rechargeable 2800mAh AAs - rechargeable in the device via a cig lighter cord, but you can throw in disposables into it in a pinch.
Worldwide on-board cartography: Not everyone needs that, but it for sure has to cover wherever you might go. This unit has a 16G Navionics Gold+ card with full global coverage, no cell coverage needed.
Marine device. This is a full-on marine GPS, will every feature you'd expect on your big plotter, but in handheld size.
