GPS Gadgets

i-gotUWe got this two GPS gadgets to play with and we would like to share our thoughts with you…

i-gotU GT-600

The little white box is actually a black box GPS device that you can take with you and forget that you have it. After couple of days (i.e. days, not hours), just download a GPS track and see where you were moving. Although marketed as a travel logger, I think it’s great for looong runs, ultra trails or adventure races. The battery can last from 30 to 240 hours, depending on the sampling frequency (1 sec to 2 minutes). There’s a single button on device that I recommend you disable through software, or else you might accidentally turn the device off (…and you will not have a GPS track of 100 Miles of Istria, for example). It’s obvious that behind the product sits a good software development team who has been thinking about configuration of device and letting you decide how you want to use it. It also has a motion sensor so it doesn’t do anything while it’s not moving (in relation to the Earth, of course) and it’s protected against water immersion (IPX7).

i-gotU GT-900 Pro

The GPS watch is a device that more people are accustomed to – you can put it on your hand and it has a display! 🙂 It can show you all kind of information: where you are, how fast you’re going, what is your altitude, how much altitude you gained… even what is the time. It uses a lithium-polymer battery (upgrade from lithium-ion batteries) and the manufacturer claims that it can work for 24 hours and save up to 200.000 points. It has a barometric altimeter, digital compass and you can pair it via Bluetooth with Heart Rate Monitor or Cadence/Speed Sensor. Lot of this features can be found in other brands, but these are usually pricy top models and if you don’t need The Brand, you can get a lot of functionality for a good price. What I found interesting and appealing is that you can configure multiple display screens (up to 16), each displaying 1-to-4 different information and you get to choose which piece of information is displayed where.

Regarding the quality of logged GPS tracks, I got better GPS track with GT-900 Pro watch, but the GT-600 track was also good enough. Despite some quirks (positioning me at altitude high above Croatian’s highest point?!?) it worked well. Because of that I learned a lot about GPS quirks, why they happen, what is dilution of precision and how to correct or simplify a gpx file. Also note that software that come with devices (@Trip PC) doesn’t display every GPS point so I recommend uploading a track file to one of the online services to see exactly how the track looks like.
