GCzII is now Approved! in GPS technology and devices Posted June 18, 2010 Incidentally, I hardly see the $6/mo as excessive. Paying $60-70 for a software license is not uncommon, and given that they're having to make a business case for it whilst still giving GC their pound of flesh, it's probably pretty reasonable. Paying $60-70 for a mobile app is very uncommon. Plus it's not $60-70, it's $6 a month. Most of us have been doing and plan to do this for more than a year. My caching has been supplemented by a mobile device since I started in 2004. That doesn't even cover the fact that GZcII blows the trimble app out of the water with features and functionality.
