Like the other i-gotU models, the GT-600 is fairly easy to operate. The only control on the device is a single prominent button on the front side. To turn the device on or off, press and hold this button for about two seconds. You also press this button to log the GPS data for your current location – you just don’t hold it down for the prolonged period.
One of the new capabilities of the GT-600 is the motion detection feature that saves battery power by automatically sending the device into sleep mode whenever you’re just standing around and waking it up again when you’re back on the move. I’m always a bit leery about devices with “sleep” capabilities, but the GT-600 seems to work quite well in this area. Even if you want to wake up the device when you’re not moving around, you can simply press and hold down the control button for a couple of seconds and quickly exit sleep mode.
The GT-600 has a built-in 750 mAh Lithium-ion battery that provides about 80 hours of life before needing a recharge, which is quite nice if you’re going on an extended trip or if you just don’t want to be bothered with frequent charging. The device comes with a USB cord that acts as both a data transfer mechanism and a way to recharge the unit from your PC. Although the initial charging of the device takes about four hours, subsequent recharges only take about two hours.
The software suite that comes bundled with the GT-600 is comprehensive and easy to learn and use. It also allows you to export track logs as a GPX or CSV file so you can use those logs with other applications. Although this software is available on a CD packaged with the GPS unit, you can also download it and install it from the product website. This is a nice option for those who plan to use the GT-600 with a netbook or other portable PC without a CD drive.
