=GPS Accuracy =
The Garmin 920XT has middling [[GPS Accuracy]]; neither the worst nor the best.
* The 920XT does well going under the bridge, an indication that it is not having excessive problems with reacquisition.
* On the out-and-back turnaround the 920XT does poorly, but no worse than I'd expect given its overall accuracy.
* Running in a straight line is a fairly easy task for most GPS watches, and the 920XT does okay.
* I've not had any issues with the 920XT acquiring or maintaining the GPS signal, unlike some other devices.

|[[File:BridgeGarmin 920XT.jpg|none|thumb|x300px| The 920xt does surprisingly well under the bridge and no issues reacquiring the GPS signal. It does poorly around the twisty section, often cutting the corners which results in a short measurement. It does okay with the sharp turn seen on the right side of the diagram. Notice that the tracks are quite spread out, especially if you compare them with the [[TomTom_Cardio_Runner#GPS_Accuracy| TomTom's tracks]]. (This diagram has tracks color coded with green indicating good accuracy through to read indicating poor accuracy, and the lap markers as blue dots.)]]
|[[File:BridgeGarmin 920XT (GLONASS).jpg|none|thumb|x300px| With GLONAS enabled, the accuracy through the bends is a lot worse, and the section with the sharp turn is also poor.(This diagram has tracks color coded with green indicating good accuracy through to read indicating poor accuracy, and the lap markers as blue dots.)]]

|[[File:AccuracyGarmin 920XT.jpg|none|thumb|x300px| This close up section of a zigzag shows the 920XT follows the line of the course, but is offset more than other devices. (This diagram has tracks color coded with green indicating good accuracy through to read indicating poor accuracy, and the lap markers as blue dots.)]]
|[[File:AccuracyGarmin 920XT (GLONASS).jpg|none|thumb|x300px| In the close up with GLONAS, the lap markers are slightly more distributed. If you look at the image below that shows direction of travel as color, you can see that the 920XT with GLONAS is having accuracy problems in the section to the right of the diagram, but only when traveling east-to-west. This is a surprisingly common phenomenon, where a watch has a dramatic difference in accuracy depending on the direction of travel. (This diagram has tracks color coded with green indicating good accuracy through to read indicating poor accuracy, and the lap markers as blue dots.)]]

|[[File:ZigZagGarmin 920XT.jpg|none|thumb|x300px| Here the 920XT displays the typical GPS behavior with the tracks that have the green lines shifted slightly down and to the left, blue up and to the right. You can see the lap markers similarly shifted. (This image has the tracks color-coded for direction, with green coming from the right, blue from the left.)]]
|[[File:ZigZagGarmin 920XT (GLONASS).jpg|none|thumb|x300px| Activating GLONAS seems to cause more a random looking distribution, rather than the clear shift of blue and green lines. However, the lap markers remain offset. (This image has the tracks color-coded for direction, with green coming from the right, blue from the left.)]]
