Polstar iGeo-Plus PBT-248- Page 3
Polstar Technologies is been one of the few companies to use Sony's GPS chipsets in designing their quality products. Polstar promises great reception levels, and it seems that Sony's 4th generation chipset is able to deliver it. In most of our tests, the performance was equal to or better than Globalsat's BT-338 which was good to see. After all, the more good products, the better it is for all users. The device doesn't have any obvious weakness, although the ability to connect an external antenna may be handy.
The low retail price of US$70.00 makes it quite interesting option, as opposed to SiRF III devices, like the Globalsat BT-338. Hopefully, the GPS community will provide more utilities for Sony enabled GPS devices, offering more advanced features.
