Other Similar GPS receivers:
These single and dual channel scanning receivers have significantly inferior receiver operation as compared to the 12 channel Blazer, the etex and the G-12 but could be compared to each other.

The Magellan Pioneer also known as gps 300 is a sequential scan receiver that is otherwise similar to the blazer. Battery life is 24 hours.

Garmin GPS 38 is an obsolete Garmin model. It is a sequential scan receiver that is otherwise similar to the Garmin12. Battery life is 12-17 hours, waypoints 256, tracklog 768 points, 1 backlight level, a speed limit of 99 knots, and no position averaging. (used models are often available at good prices.)
