Ymmärtääkseni kuitenkin noissa Garminin T-malleissa on karttana Garmin Recreational Map of Europe:

 

 

Kyllä sillä kätköilykäytössäkin jotain tekee. Tämä siis erotuksena kaikista malleista löytyvään maailman peruskarttapohjaan:

 

 

Yleinen harhaluulo on, että tuolla peruskartalla kuuluisikaan tehdä yksinään mitään, sen tarkoitus on lähinnä toimia nimensä mukaisesti karttapohjana suuremmilla zoomaustasoilla:

 

 

Tämä ei tietenkään poista sitä tosiseikkaa, etteikö Suomi Pro -kartta olisi ylivertainen tuohon Garminin Eurooppa-topoon verrattuna.

With all due respect vinnemon, the calculated accuracy figures are limited in their meaning and usefullness. The equation used to calculate accuracy is subjective. What really gets to the issue of accuracy is position calculation. The accuracy number may or may not be indicative of the better position calculation that is appearant here. In other words, you might be right, the better accuracy numbers on the unit itself may reflect the appearant improved positional accuracy, but not necessarily.

 

More of the question of accuracy would be addressed by collecting some data. It would be helpful to turn the unit on and place it in a stationary position for a period of time to see how much variability in the position calculation there is. One way to do this is to turn the track on, reset the trip times (stopped and moving) and observe. A benchmnark test would be another good one. Also, a track comparison with other known accurate units with some variable conditions such as tree cover, hilly terrain, and sinuosity would be great.

 

I plan to grab my buddies 60CSX and run a comparison tonight on some trails behind my house. I'll post the results.

 

Well yeah, I know, that was just a single observation.

Yes, the accuracy has improved with this new GPS software version! I got accuracy of 2 meters (6 feet), when before it was in the range of 5-6 meters.
