Is Magellan's Meridian Platinum really that far off ?
Posted 05 October 2003 - 05:38 PM
Now that's embassasing. I've tried feverously to set the parameters, and even set it back to factory defaut, but still no luck. I sent Magellan's CS a message tonight, and don't know when I'll hear from them. So I thought now would be a good time to pay my first visit to the famous Geocacher forums.
Thx in advance

Maybe this is the reason? Any Meridian owner may be able to give better information.

When I get about 100 ft. from the cache I stop and look 100 ft ahead of me. I know the cache is between me and that point. I look around without moving. This gives me the lay of the land and allows the GPS to catch up with me. After a few seconds the GPS will tell me the distance and I begin my search.
I went for a cache with a friend who has a Garmin. You are right, he went right to it. But he also had trouble getting signal in the trees. Decide which you prefer, poor signal or rubberband effect.

What I do to combat the problem is I go until my GPS says I'm ~50 or ~100 feet from the cache. I then turn off my GPS for a moment and then turn it back on. This seems to clear the "averaging" and it will better point me toward the cache.

I too have learned to stop 50'/100' from the cache, put the GPS down and start looking, a couple min's later I will go back to the GPS and usually follow the arrow and distance right to the cache. I am amazed at how accurate it usually is....I'm not speed caching, so the slight time lag doesn't bother me.
Experience is something you don't get until just after you need it.

On the ST Pro, I've found that if I stop immediately when the 100' alarm goes off and hold the unit in a good upright position away from my body and let it settle out (usually will settle around 85') then proceed to 50' and do the same, I can then walk right to the area of the cache. Turning the unit off and back on as somebody else suggested does not seem to work well for me, as the GPSr seems to lose accuracy when I do that. The 330, on the other hand, is a different story...
No matter what sort of stop/start pattern I've tried with the 330, it always overshoots the cache. The 330 doesn't seem to lose accuracy by power cycling it, and doing so _does_ clear whatever variables in the software are causing the averaging perfectly. So, with the 330, powering down and back up is the answer.
Also, my ST Pro seems to handle the transition from moving in a car at 45 MPH to walking much better than the 330. With the 330, I used to make a habit of power cycling after getting out of the car (position would literally change by 80' or so), whereas the ST Pro seems to understand 'oh, he is walking now; better clear that average!'
These are purely my own observations. Your results may differ.

But today I learned differently when I tried a GPS course that was set up in my town (ten points, in fairly open areas). At a few points the GPS said I was 50 ft away, after I shut the unit off, then on it read 4-5 ft away (I am not sure what kind of equipment was used to determine the location, but I assumed it to be fairly accurate). What was kind of odd is the first two points of the day were within 5ft, the only difference between those two, and the rest is I turned the track on.
I have version 4.06 in my unit, but I may downgrade to 3.12 since I have had similar experiences with 4.06 in the past (when ever I send my unit into Magellan they keep upgrading me to 4.06). I can't say I experienced this with 3.12.
The probability of someone watching you is directly proportional to the stupidity of your actions.

My ST Pro is running v 4.06
The 330 is running the 'unofficial' v 4
I've never realy noticed any difference with the track log settings, though I usually run the track log on 0.01 mi. I, for fun, sometimes like to overlay them on USA Photomaps to see where I've been.
From the perspective of a software developer, I tend to think that the track log observation is just coincidence (logically, the two parts of code would be mostly unrelated). I could be wrong though (it has happened from time to time).

While it's not really part of the subject, the unofficial v4 is only sort of unofficial. If you call or mail Magellan/Thales and annoy them enough, they will mail you a physical CD that has the 4.0 image for the 330 on it. It is, for example, included on the second CD that's int he Topo 4.20D distribution.
If enough people do this, perhaps they'll be more motivated to find the root password for their web server and actually update it instead of paying UPS to deliver round shiny things to people's doors...
I think I'll sign on for a piece of that action...That looks really sweet.

Or just get 4.0 at the official Magellan Australia website

I have a MeriGreen and a eTrex Camo. The only trouble I've had out of the Meridian was on a day of very high sunspot acitivity, the unit kept telling me that I was very far away from my actual location and elevation. The eTrex came through for me that day. The only real problem I have with the eTrex is that it loses the signal often when under any type of cover and always if the unit is not held horizontal.
Having said that, the G unit does seem to aquire signals more quickly than the M unit that I have. I play one against the other when out caching. I think the advice here is to STOP MOVING for a few minutes when you get within 100ft or so (no matter what brand you have) and take a look around. Often, you'll get the score more quickly than if you run in and start beating the bushes.

I can't believe that that is the 'norm' for Magellans. Surely it isn't. When we were caching side by side, mine was right on and his still had him walking up the trail 50 feet.
About that, I would take a Magellan with slingshot effect anyday than an inferior antenna (from experience) and that damn 4-directional click stick (no diagonals!)

No wonder Magellan owners spend so much time in the forums Takes them so long to find a cache, they'd rather stay home
The Vista's click stick seems to work diagonally for me anyways. No complaints.
Remember these words when we're caching and you're like 50 feet away..."Here it is!"

As I understand it, the Magellans lose signals just as often as Garmins, but they just don't tell you right away. They continue to try to project your course for a while before they give up. The Garmin just tells you that the signal is gone as soon as it loses it. So the Magellan appears to have a signal lock when it in fact doesn't, which feeds the perception that Magellans get better reception than Garmins.
And yes, the eTrex must be held properly (flat, or upright) to get a signal. This is another reason the eTrex is maligned for its reception. If you hang the thing around your neck, you will lose your signal, but if you hold it correctly, it locks on and holds its signal quite well. There are times I take my Vista, or Gecko out of my jacket pocket and find that I still have a signal lock.

Magellan needs to have a setting on their Meridians that would be greater than AUTO DETAILED, also there needs to be a setting to allow the tracklog to segment with each power on. They need to put in screens with a resolution of 160x240 to improve readability.
Posted 03 February 2004 - 06:44 AM
You're free to argue that reception inside an house doesn't matter, but this clearly isn't a matter of the Magellans "faking" reception or not telling you you don't have lock while the Garmins are being more honest.
That said, I've been on hunts with those units in the hands of their respective owners and we've never blamed a purple frownie on equipment failure. All the units got us to the caches; it was a draw which one got us there first. As a practical matter, once you're within a few hundred feet or so, geo mojo will get you there more reliably than a GPS anyway...

we also have a lovely satellite window which displays exactly how many satellites you are receiving and how strong they are. What I have read about here appear to be non issues.
Posted 03 February 2004 - 09:51 AM
If yo set your track detail .01 that is quite a bit more detailed than AUTO DETAIL.
Also, with my experiences with Garmins, i had my Magellan set to beep when it lost lock, because of the fact that they dont tell you when you lost lock. Even still, the Garmin was losing lock, and becoming completely useless, while the Spotrac was keep a fine lock, in the car, and under decent tree cover.

I am quoting to try to stay on topic.
For best result, use as directed below:
1) Turn on a few minutes before use, to aquire a good signal, then check the satelite page to see if there are enough satellites spread out good.
2)When you get out of the car, hold the gps still for 2 or 3 minutes with a generous view of the sky, then do your GOTO
3)when you are walking to the cache and it cuts out, stop and hold it high for a couple minutes to recover while standing still then move on.
4)when you are near the cache, stop and stand still for a couple minutes, to take your bearing on the Platinum, and let it settle down, if not find a clearer opening in the tree canopy and try again. Dont be too hurried to find the cache, take your time.
If all this fails, check these:
1) What is the quality of Position of the sats on the Satelite Page?
2) Are the trees wet, and are the trees too thick between you and the Sky?
3) Are you holding the gps so it gets the BEST view of the sky?
4) Are you taking the time to let it get a LOCK?
5) Are you TOO hurried?
IF YOU ARE CIRCLING, then one or more of the above aply
When I followed these things, the GPS performed great.
Have a second GPS available to compare if your GPS is crapping out.
Usually severe problems can be ironed out with RESETTING and/or Reflashing of the unit.
When I followed these things, I had fun and usually found the cache, as long as the cache is not way off it's recorded position.

Actually I sat with a stopwatch and timed my Meridian Platinum (v5.12), and my GPS V (v2.50)-I need to get a life. It appears that the Magellan will tell you on average a few seconds sooner than the GPS V (the Meridian always alarmed first).
I have owned a Meridian since they were released in October 01 (and before that a 330, and a 315), and the GPS V for several months now. From what I can tell the Magellans DO hold a better lock.

We recently checked a set of coordinates for a cache we are working on. The coordinates are in the middle of a highway (not a very busy road though). We went from 65 MPH to 15 MPH and then to 10 MPH and the unit showed within 10 feet of where we had stood to mark the spot.
If you can go from 65 MPH to 10 MPH and get a reading that close you learn to trust your GPSr.
Maybe we just got lucky and got an exceptional GPSr.

I use V4.03 is there a newer verson for the green meridian?
Posted 21 May 2004 - 02:56 PM
My guess is that you are either holding the unit the wrong way (you should hold it at a 45 degree angle), or the satellite signal is weak due to sky obstructions.
Check the satellite geometry as well... Make sure they are spaced out and not all grouped together on one side of the "sky". This does make a difference.

There is a 4.05 out for the Merigreen/yellow. I think that the latest version took care of some incompatibility problems with newer SanDisk SD cards. If you're not having any problems, there are no new features to warrant upgrading.
