Fox Gap

I just bought a Etrex Vista (had an old Lowrance) and was wondering if buying the topographical software will help me out at all. I haven't received the unit yet, but am looking for any info from someone familiar with the topo maps. Can't wait for my first geocache experience!

Thanks for your help!

This is my first time doing geocaching and I have a quick question. I have a old Lowrance GPS (1994?) and want to upgrade to a newer unit that works best in NJ and PA and is best for geocahing. Does anyone know a good unit for under $250?
