Re: Portable GPS that does marine too?
Nick: I have a Garmin Etrex Legend that I use for backpacking, geocaching, boating and sometimes in the car. It is kinda hard to use in the boat (and car) because the display is small and the buttons are hard to use if the unit is mounted (vs handheld). It is great for hiking though.
I have been looking for a marine unit - but they are expensive. I recently came across the Lowrance XOG - which they market as a crossover unit - it can be used in a car, with visual and voice turn-by-turn directions. It can be used in a boat, with water resistant construction and a SD card slot where you can install stardard marine charts from Lowrance, Navionics, or Fishing Hot Spots. The unit can also be used hiking with it's built in rechargable battery (only 2.5 hours though).
The XOG is much, much easier to use in the boat. The touch screen is easier to use than the side buttons of the Etrex. THe XOG screen is about four times larger as well. At first I was a little disappointed by the built-in base map of my local boating areas. My old Etrex showed the coast guard bouys - but the new XOG does not.
I went back to my dealer and bought a Fishing Hot Spots card for $50 - this made a huge difference - now I not only have the coast guard bouys, but also all other aids to navigation, increased shoreline detail, water depth contours, and marina info. It even shows the best fishing locations and provides info like bait suggestions and fishing technique.
The XOG comes with a suction cup windshield mount and the 3.5" display screen shows much more detail than my old handheld unit. I am very, very happy with the unit - both for the boat and car. I will keep the Etrex for hiking though - it is a little smaller and the batteries last 20 hours (because the display is so small ?)
My wife really like it too - now she wants one for her car.
Oh ya - I paid $260 for it locally
