RGM-3800: Royaltek RGM-3800 GPS Data Logger (SiRF III GSC3f/LP, WAAS, 650,000 Waypoints) Review

Average Reviews:

(More customer reviews)I received this as a Christmas present to use in conjunction with my camera to GeoTag photos. The one down side of this is that the customer support is rather poor, leaving a question on the RealTek website's support form only results in a response that I should use the form.

I am using this with Linux, the software that comes with the item is for Windows (Mac?) but after finding the source code for a program to read and set the parameters in this device it became very easy to use.

The UI (User Interface) consists of one on/off button and a red/green LED. Other than that there is nothing else but a USB port. I have used it indoors and it has acquired satellites in 10-15 seconds, Outdoors the time is lots faster.

The logging interval can be set from 1-second to 60-seconds. At 15-seconds this will record about 500,000 data points

It will capture about 180 (12hour) days of data, but the batteries need to be replaced after 6 - 10 hours. I use rechargeable (2 AAA) NiMH lasting 8 hours. RealTek claims 10 hours on Alkaline.

The shell is White. But that is an advantage, it is visible and easy to find even if dropped in the weeds when out on a photo shoot or hiking.

If I lost this one would I replace this with another - YES!
