Query: Geo-Cacher Dream

I purchased two of these unit recently from Amazon and I could not be more pleased. The units are highly sensitive and find the signals quickly. The time quoted as 24 hours continuous use appears to be accurate. I also purchased the TopoMaps 2008 on the DVD and a 2GB disk and I am glad I did. If you are into hiking or geocaching this light, bright unit with a 2GB card will get the job done well. CACHE ON
