Thanks for the responses. Maybe it is the position of the satellites that is causing different accuracy readings. Maybe is was just chance that when the reception was bad that it was always cloudy. My battery life in cold weather is not very good with the 76S, an external that runs off its own battery really appeals to me. I have found that when I am getting 10-12 feet readings that my ability to find caches goes up considerabely over my ability to find things when it is at 25-30 feet. Thanks.

Thanks for the responses. It looks like it definitely aids reception. The Gilsson also seems to be quite a bit cheaper than the Garmin product. Does anyone have experience with both? It would seem to be a big advantage as when the leaves are on the trees, it is sometimes hard to get a good signal. Thanks for all the help.

I have a Garmin GPSMAP 76S. Since I updated the software to the latest version 3.6 I have been happy with the unit. Does anyone have experience with the optional external antennas? Do they help? On clear days I can get down to 9-12 ft. On cloudy days 20-30Ft. Does the external antenna help those numbers? Can they be used walking through the woods? Or does it only help in big cities with lots of tall buildings? Any feedback would be appreicated.
