My husband has been using a garmin GPS12 for years. It is a basic older
monochrome handheld unit. We now use it as a back up for our fixed
mount standard horizon GPS. I would recommend a Garmin unit. Hand held
of small fixed mount. I have found their units very user friendly. They
also have a good warranty. When looking around, know that West Marine
has a price match guarantee. You just have to bring them either the ad,
print out, or quote of a new item. West Marine also has a Product
Protection Program. You can get up to two years after the manufacturers
warranty. Plus, it is always nice to walk out with product in hand then
wait for it in the mail.
