I was poking around on Amazon.com this morning and found the gadget of my dreams–okay, I was actually going there to buy some books–but a recommendation popped up for the a href=”http://www.amazon.com/gp/product/B000CSWCQA?ie=UTF8tag=wwwviolentkicomlinkCode=as2camp=1789creative=9325creativeASIN=B000CSWCQA”Garmin Forerunner 305 Wrist-Mounted GPS Navigator and Personal Training Device with Heart Rate Monitor/aimg src=”http://www.assoc-amazon.com/e/ir?t=wwwviolentkicoml=as2o=1a=B000CSWCQA” width=”1″ height=”1″ border=”0″ alt=”" style=”border:none !important; margin:0px !important;” / and I had to take a look. Why? Because I have both a bad heart and a lousy sense of direction and I had to see what kind of technology was available that would address both of these shortcomings. Here is what I found out: br /br /blockquoteJust when you thought Garmin had cornered the market on powerful, affordable, and effective wrist-mounted GPS devices, here comes the Forerunner 305. The release of this device is a major achievement from a design and technology perspective. This isn’t just marketing-speak; the Forerunner 305 is the most accurate, most reliable wrist-mounted performance and GPS tracking tool we’ve ever tested. Yes, it’s that good. /blockquotebr /br /So for runners and for me–a walker–it apparently tracks one’s heart rate and other exercise stats and also marks one’s location and provides a simple map that displays your current direction and path. That sounds pretty amazing if it really works. I would love to have one of these devices for traveling or when I am not familiar with an area I want to walk in. br /br /Before I spend a couple of hundred dollars on such a device, has anyone out there used this thing or something like it, or do you have any other suggestions for GPS gadgets?br /br /Update: What I really need is a GPS system for my car–does anyone know a good one they can recommend that is easy to use?
