oregon 550 bad low speed reading

Former Member over 13 years ago

Used for hiking, my Oregon 550 works correctly above 2.0 mph. But at 1.9 mph and slower the "speed" reads 0 mph. this affects other readings like average speed and direction etc. I have upgraded the software to 5.0 with no affect. I have looked for a "stop time when not moving" setting to see if that is the problem, but could not find it. Any ideas?

Record method & Interval

As a fellow O550 user to another, check your Record method & Interval under Setup/Tracks on the unit. Set to suit. This may refine your observations. Changing your profile from automotive may help.

sarlabs - I checked the Oregon wiki.
the GPS Receiver & Satellite - bugs says-

The Oregon reports and detects too much stopped time when being used at walking speeds. As compared to other Garmin high sensitivity receivers the Oregon periodically reports a Speed of 0 mph even though the unit is moving 2-3mph. Speed fluctuates significantly at low speeds and Stopped Time increments as a result. (2.98)

(2.93) Improved GPS reception. GPS performance is very erratic with 2.86 software with sometimes large (100'-200') errors observed. Reported accuracy numbers have improved but actually accuracy is much more variable. Unit is more sensitive to movement although the "too much stopped time issue" seems to still be a problem. (2.86)

After upgrading to 5.0 software, and more testing, it seems to read the correct mph down to 0.6 or 0.5 mph. works much better
