I LOVE geocaching!!

I started in 2010 and got my boyfriend into it. We almost got a GPS for Christmas but I'm still not sure which is best for us. We were looking at the Garmin Dakota 20 and the Magellen explorist. Right now we just use the app on our phones. It's been too cold to geocache! Luma has only tagged along once or twice.
Which gps model do you have? I've been waiting for a YTer to come along that knew about geocaching
