Hi, I need advice on which GPS device to purchase to map structures in camps
in Sierra Leone. I need something durable, that has a large memory (will
need to measure over 3000 points), very reliable as the data will be used
for public health measures. It may be cloudy as I will be there during the
rainy season. Must use batteries as there is no access to electricity,
cannot be rechargeable. I will not have a computer with me as it is not safe
nor, again, will there be electricity. So it is important that I find a
device that either has a large memory or capable of adding memory so I may
upload the data when I return home to analyze it. This is not recreational.

Thanks for your help.
