I think the Geomate is much too kiddy for a teenager like myself. The explorist would only cost about $20 more since it's on sale right now where I could buy it. Regardless, they both look pretty good for a beginner like myself. Just looking at the specs or maybe you own one, which one to you think I should go for? I'm going to buy it Monday (today due to time) so quick answers/comments would be nice. Thanks.
