The eTrex 30 states, "The eTrex 30x can also be connected wirelessly to other GPS or sensors that are so enabled. This is great for sharing waypoints, routes and tracks with hiking partners and also pairing a cardiac strap or foot pedal."
That sounds weak...I have no need to connect to other GPS. But if it has wireless capability, why not use it to download caches?? And , hence, why I posted the question. I was hoping you'd tell me the 30 would do the job!!
Thanks for the replies.
