Just so I get this correct. The red path is the real path that you walked and the yellow path is the one that the GPS said you walked?
You are right.
but I can't reproduce it (yellow line) again

The eTrex Legend doesn't use the SiRF chipset so it isn't as sensitive as ones that do like the GPSMap 60Cx. As such it is more easily confused, takes longer to get a lock, and needs a better view of the sky.
I read HCx has SirF III chip (as Vista HCx), but can't find the link now. The letter H - stands for High Sensitivity receiver.

The HCx uses a different chip, I don't know the name of it. Have you updated the firmware etc for your GPS? That can sometimes fix tracking errors.

The firmware is original.
Shop clerk said the chip is the same between GPSmap60 CSX and Legend HCX :(

I decided on the Colorado 300 and it uses a new Garmin proprietary chip set which is claimed to perform on par or better than the SIRF chip in the Garmin HCX series. It has the built in electronic compass and altimeter and a nice, big display for a hand held unit. I have no grounds to compare but I get really good reception in all kinds of conditions ranging from heavily treed conditions to indoors. I get a signal sitting in the house several feet from the windon. Steveston Marine has most popular models on display and their "sale" prices on their web pages are pretty competitive if you want to see them locally. The best pricing I have found is GPSCity in Calgary. They have virtually every GPS, accessory and RAM mount in stock and even if you include freight to your door their prices are excellent. I get overnight service for less than 20 bucks andconsider you don't have to pay PST they are very competitive. Theymade a shipping error on a RAM mount part and I had the correct part the next day no charge and they told me to keep the old part. I would highly recommend them.

Since I lost my 276C. :mad3:I have been looking for a new GPS. I ended up getting the Oregon 300. It is just like the Colorado 300, but it is a touch screen. It even works in my house and is veryaccurate.

The reception is much better than 276C. The 276C always worked fine on the road. It would not work in the house and would cut in and out off road.

The things I don't like are the smaller screen than my 276C and that it is hard to see in the daylight. I have just been using cheap batteries. I hope it is better, once I get it wired to the bike.

Yep Oregon/Colordo 300 has the same specs except touch screen and build in memory (850MB/384MB respectively)

They look pretty easy to navigate and have good monitors

I went to DiscoverGPS.
The service was just .... bad. The guy didn't have answers to our questions, and didn't care. I asked about Legend HCX, Vista HCX, and 60CSX. Finally he said he didn't know much about those, because he uses something much better. :shoot:

If you are looking for good service and prices I would recommend GPSCity in Calgary.

<<gpscity.ca>>

They have the Colorado at $349 after a 50$ rebate. They usually have RAM mounts for them in stock as well as cables. You can get 1 day service from Calgary for $20 and there is no PST.

Discover GPS did match the GPS City price. But all they had in stock was the GPS. No topo Canada maps and no ram mounts. I was told they would ordered them in for me. I got the feeling that was never going to happen. It's been 3 weeks and still no Topo Canada or Ram mounts.

Right after I got the GPS I ordered a Ram Mount from GPS City and got them the next day.

Discover GPS also does not take debit cards.

On some GPS's you can set them for marine, automotive, trail, etc. I am thinking if it was set for the road, the track would stay on the road.


On the Oregon, I can go to "Profile Change" and I can select different profiles. Trail, geocaching, automotive, marine or fitness. In automotive the track just stays on the road. In the trail mode, the track will go anywhere.


On my 276C I could chose marine or automotive. In the automotive mode the track would just stay on the road.

Hi Lucky:

I'm certainly no expert, but:

Your trackpoints are very close together and only 5 secs apart. The GPS is trying to interpret the track based on rapidly changing (ambiguous) directions in a short period of time and distance,(ie 5 seconds and around 7 meters).In such a short distance the GPS would interpret any small change in direction and estimate it to make the track.

It appears you were moving very slowand if you're going to use it while moving at a slow speed set the trackpoints timebase to a longer period, so the machine can do the calculation based on more information. According to your chart there was considerable variation in the direction as you moved that wouldn't happen on a motorcycle or car at higher speed.

A GPS calculates position based on changes from one point to another, and the more datait can collect andaverage the more accurate the track.

I think...

No, I can't see options to change a profile.
When I set a waypoint "GoTO" a device asks Road/OffRoad, but it doesn't relate to sensitivity etc.

It could just be a distortion in the time and space continuum.:shock:


"Road" would be Automotive and "Offroad' would be Trail.
