Location: Waukesha & Land O Lakes, WI | GPS accuracy can be summed up like this.
1) When you're recieveing the WAAS (Wide Area Augmentaion System) signal, you're gps should be accurate from between 10 and 50 ft.
2) If you're trying to use "electronic maps" on your gps screen to try to establish accuracy, you'll never do it. GPS will always have error and the lake maps are never perfect. Combine the two and there's your wide range of inaccuracy. Now I will say this, some lake maps are more accurate than others. Winnebago, when it fisrt became available, we notoriously in accurate.
Electronic lake maps are a guide, not to be used as a sole navigational aid under any circumstances.
The "upgrade" to your 162 was probally the WAAS upgrade that I know Garmin made available. |
