The accuracy of the GPSr has no relation to the accuracy of the maps installed.
I'll check back in around Dec. 15th.
Really. I believe this subject deserves/merits it's own thread. As a long time user I am very curious how we find ourselves back to pre Selective Availability levels of GPS performance. I noted a similar observation in a different model specific thread and thought it would be good to consolidate the info in a singular thread.
I'm not sure how this suggestion could be construed as an attempt to silence anyone.
I stand by my full post as I wrote it, I regret the manner in which you selectively quoted me and how you interpreted my original post.
Well, precision vs accuracy should have been obvious to me as a marksman for many years. When you shoot a new rifle for the first time and you want to know how accurate it is, you shoot a group to see how close five shots are at 100 yds. Say your group is 1 inch in diameter. Thus the precision of the gun is one inch at 100 yds. However, your group is 6 inches low and to the right of the bullseye, so now you fiddle with the sights or the scope until your one inch group is centered on the one inch bullseye. Now you have a precision of 1" at 100 yds and an accuracy of 1" at 100 yds....= dead deer!
So I am guilty of misusing these terms...my bad.
Many here are rather sick of all this fuss over these concepts since the Montana obviously has adequate accuracy and precision to get us where we need to go on a bike every time (not counting auto-routing peculiarities). I've been using min for 2 1/2 years and never suspected it was not accurate to within about 10 feet.
Now that I do suspect this, I simply want to know what I can realistically expect if I ever need to use it for something that really does depend on both accuracy and precision, like finding the outhouse 50 yds. away in a whiteout with 3 foot visibility. (No, not really, but say geocaching)
So I am going to search out some USGS survey markers over the next week or so to see if its accuracy is as poor as its precision plot predicts.
(Poor being a VERY relative term here....I already know it's just fine for 99% of what I will ever use it for. It's that 1% that bugs me.:eek1
I think a new thread is warranted if there is data from other units to compare it to. Right now it's pretty much floptana so it seems reasonable to keep this part of the discussion here.
I have solicited folks to send me tracks from whatever units. So far only one poster has asked how to do this with something aside from floptana....
Your one comment wasn't construed by me that way. What I meant is it seems to me there is a very clear message from some folks to shut this discussion down in this thread. I don't tend to bring it up unless someone else does or there's new data anayway.
There has also been a smaller group that seems to send very clear message when any negative topic regarding this unit is discussed more than a couple of posts.
Oh well. It's just an internets board...
Not a problem, I would like the subject to see more daylight and wider audience then it may receive buried in a 600+ page thread. In the MC model specific mega threads I have seen many really good subjects/discussions get lost due to the shear volume of material.
At the risk of being jumped on by another certain member, I visit this thread because I am interested in all things GPS, and not owning a Montana I'm not seeing the world through rose colored glasses. Feel free to check my profile for my previous posts, I don't have an agenda and like to think I have helped others and been helped by others here. While there may be a post or two I would like back I stand by them.
My posts here are themselves becoming redundant and having had the opportunity to give input will be watching from the sidelines.
I completely agree. If I can get enough other users to start providing logs, particularly with other units, I will jump on creating a new thread. The logs are very easy to create. I can't do it all by myself - I don't have enough units. Anything new that comes up regarding floptana we can mention here and provide the link.
OTOH I'm not so inclined to do it if there's not enough interest in collecting data. Partly because I know there are others that just want the discussion to "go away"!
I also agree that this topic should have it's own thread. I would like to see more data, especially on other handhelds and maybe the new zumo390LM or a Samsung GS4 using an app that records a Track Log.
When I'm not on the road, I'm usually focused on how the software and UI work/or don't on various GPS units.
This type of effort keeps the Mfg's from getting too sloppy so I'm all for it. I also think it should be visible to all and put in context to daily use of the device by the "average" user.
found another glitch, i have 2 profiles one motorcycle one auto, on my mc profile I have it set to record/show tracks, auto is set to record/ dont show
not really sure what exactly causes it but if I change profiles and enter/exit setup it will switch my auto profile to record and show
There is now a small system update out that does something to the time zone database.
I was using my Montana this week and driving from one time zone to another and it showed the ETA based on the time zone I started the trip from vs. the time of arrival in the time zone I was going to. When I crossed the time line the ETA then revised to the time zone I was traveling to.
This is different than my nuvi as it has always displayed the time of arrival for the time zone you are arriving at from the very first. Maybe this update addresses this issue...
I assume this is new feature on all new generation units. It is settable (fixed or Auto) in setup on my 78.
What firmware version are you running, and what is the kb size of the gmaptz.img in your Montana\Garmin\ directory?
age old question chicken or egg...start the thread,they will come
Maybe we should just have a unique thread for each user, where they can control the subject matter to meet only their desires, sparing them from opinions and conversation that is not their own?
Or, you could just start a twitter account and only read your own feed.....
I'll keep it brief.
I really don't care how much negative stuff you post about the Montana.
Calling it floptana over and over again just makes you look like a knob.
That's rich, coming from the sole contributor/owner of the Montana Wiki.
