I use an iPAQ that has no model number but I use GPXSonar with it. Little or no problems and it works great with GSACK. Ken From: christianherper@xxxxxxxxxxxxxxx: geocaching@xxxxxxxxxxxxxxxxxxxx: [GeoStL] Does anyone use an IPAQ Date: Wed, 6 Feb 2008 22:03:36 -0600 I just bought a used iPAQ Pocket PC Model H3650 on e-bay. Do any of you use this PDA for caching? If so what do you think of it? Thanks! Eric _________________________________________________________________ Climb to the top of the charts!
