Silva claim that the latest model sustains much longer use - up to twelve hours. When not in continuous navigation mode a single position fix takes about one minute, though the first fix in a new region will take longer, as will fixes performed when reception is poor, such as in bad weather or in forests. The Silva GPS compass will be useful to professional geologists working in areas where base maps are relatively poor or where the safety of the working group is paramount. One purchased for such a purpose, however, is likely to find itself employed at the weekends by those professional geologists who enjoy hill walking, yachting or rallying. In conclusion, this is a useful, reliable, and attractive GPS receiver and compass and we look forward to the price falling as the market matures.
