I am looking for a small programmable gps unit with a simple LCD display. I want the gps to work in two modes:

  1. Display geographic (degrees north and east) position coordinates.
  2. Display position on a paper map e.g A3 that I have georeferenced before hand.

For instance if I were going to Barcelona I would print out: Barcelona map. Next I would read the position of the corners of the map in Google Earth and I would program the device. Next I would be in Barcelona wondering where I was. I would read F6 off the device, look it up on the map and find that I was near Porto Olimpico.

The device should preferably be small, have an accurate and fast gps, waterproof, have long battery life and be readable in bright sunlight.

  • Why do you want to relate this to a paper map? Any tablet with access to mobile data will display a map of your location. Why is it better to use a paper map? – DJClayworth Feb 10 '16 at 17:23

    A paper map is foldable, light, and have infinite battery life. My example was in a city but I think would use this solution mostly in the wild. For instance I like sea kayaking and bring a plastic covered paper map on the deck of the kayak. If I could throw a quick glance at my wrist and read of e.g. F6 I would immediately know where on the map I was. – Andy Feb 10 '16 at 17:51

    Fenix 3, but you'll have to convert long/lat onto your map – WW. Feb 11 '16 at 11:41
