    Satellites

    in GPS technology and devices

    Posted · Edited by vr12

    All geostationary satelites are located in equator plane which means atleast three things:

    1. You will not be able to resolve between south/north hemisphere.

    2. latitude resolution at the equator would be horrible, my guess is >100 km

    3. GPS sattelites at north/south pole will be too low to see.

    If markup is 5-10% then I  don't understand how RadioShack is still alive.

    There must be something which has 50-80 % markup

    It is called volume sales. Besides, about the only thing radio shack sells anymore is cell phones.

     

    80% in retail I do not know were anyone gets the idea that it does happens, it may in some over priced store in Beverly hills were people have more money than brains. :)

    50% may happen in the clothing industry becuase the stores need to carry a size range, they cannot buy just say a Medium shirt, they have to buy a size run. Some of which will have to be discounted at the end of the season. A size run may be 1xs, 2sm, 2md, 2lg, 1xl. with hard goods (Non clothing) a retailer can order just one of an item in most cases, unless it is something real cheap then they may have to buy a dozen per order.

     

    I always hear people that have never been in retail claim that retailers make a high mark up.

     

    VR12. go start a retail store, then tell us all your big markups in the land of fantasy B)

    Volume sales in RadioShack ? :)B)

     

    BTW markup doesn't include rent, it just markup - difference between buy and sell

    How Bad Is This?

    The unit in question is a Garmin eTrex Vista, and the

    guy is asking $75 US for it. He says that he used it for

    boating and has given it up. I know that it sells for a

    lot more than that brand new (more than I can afford!).

    Vista is 12 channel reciever, don't think, take it for $75.

    Garmin 60cs Questions...

    in GPS technology and devices

    Posted · Edited by vr12

    3. If I buy the City Select and add it, does it clutter my screen? I mean is there a way to turn off the restaraunts, etc? I cannot imagine when I add additional highways, streets and then all that other stuff. I want to be able to SEE where I want to go!

     

    >> 3. Yes <<

     

    So it clutters up my screen?  Or is this a yes, I can turn it off? 

     

    CajunSis *who really appreciates your answers...

    I meant - there is a way to turn off clutter

    If you have 60CS already you should see "declutter" option in the map page.

    1. it is the way to prevent software piracy

    2. City Select have autorouting and MG (except version 4) doesn't,

    City Select is pretty much "must have" when you buy 60CS.

    3. Yes

    4. Yes, no matter what you will be able to have 1000 waypoints

    Question On A Garmin 60cs

    in GPS technology and devices

    Posted

    I have a subsidiary question about the calibration of the 60cs compass. It says to turn slowly for two full turns.

     

    Sometimes I turn the unit, sometimes I shuffle myself round on the spot as well, but either way it's pretty hard to maintain a constant speed.

     

    The progress bar fills up after somewhere between 1.8 and 2.2 rotations. Does that mean that my compass will be 10% out, or is the unit smart enough to cope with the inevitable minor variations in rotation speed ?

    it doesn't mean anything, Just don't rotate too fast and hold level.

    Magellan Vs. Garmin

    in GPS technology and devices

    Posted

    Now the eXporists puzzle me.  For all intents and purposes they seem to just be Magellan brand Garmins.

     

    This is not correct, You will not find a Garmin Hand held in which you can expand the memory wth an SD card, which you can do with the explorist 400, 500 and 600.

    The exlorsist also give you the option is storing waypoints in a file system, you can have several thousand way pints store in files that can be broken down to regions, cache type, cache ratting and so on, this is also a feature that is not offer in a Garmin.

    You can also store more maps on an exlorist with the SD card.

    The Magnetic compass in the explorist 600 is traxial which means you do not have to hole the explorsit 600 level for the compass to be correct.

     

    Will any of this make it easier to find a cach, No.

     

    Wow, thanks for the awesome info. The "boomerang" effect you speak of, is that where the GPS shows the destination beyond where it really is, and you overshoot, then it corrects and you come back? I just have never heard anyone use the term except on these forums
    .

     

    The explorsit do not have a boomerang effect, the OP is asking about the explorist and not early magellans.

    I believe standard complain is that you cannot sort these thousands waypoints by name. in any case I don't see a need for having thousands of waypoints.

     

    The only thing (in my opinion) which is better on Magellans is SD-card slot.

    76cs How Do I Question

    in GPS technology and devices

    Posted · Edited by vr12

    I need to erase all the city select and topo maps along with all geocaching waypoints.  In other words, recover all my memory so I can load the new maps and geocaching stuff we will need during our vacation. 

     

    I thought there was an easy intuitive way to do this but could not figure it out.  I left my owners manual in a hotel room and now my home computer is in the shop.

    Not allowed to copy personal stuff from work.

     

    Thanks

    If only I got a nickel every time I see that question :D

     

    You don't need to erase maps, they will be replaced when you load mapset into GPS. as for the waypoints You can delete them all at once from Menu:

    Find->Waypoints->Menu->Delete->All Symbols

    Is Is Possible To Change The 64 Mb Chip In A 60cs

    in GPS technology and devices

    Posted

    Brighter minds than mine have suggested that the firmware (that resides on a separate chip) would have to be modified to recognize that you had a larger RAM chip. Also, the basemap resides on the map chip, so replacing it would lose the basemap. If the firmware could stand it, I guess you could replace the 64MB map chip with a formatted empty 64MB chip and get an additional 8MB that way, but I wouldn't recommend it.

    I think 60C firmware will recognize 128MB chip because it is the same in 60C and 76C.

    As for the basemap, one in principle can copy it on a chip to be installed.

    All I Can Say About My 60cs

    It's also working great for me.

    The only thing at the moment that I can think of thats useless (to me at least) are the games. If those were scratched I would think it would free up quite a bit of memory to add the additional features and more that we would want in the future (such as longer waypoint comment fields, names etc.)

    Firmware and data use different memory, you cannot use memory where firmware located for data.

    You have no choice but play games :lol:

    Explorist 600 Problems

    in GPS technology and devices

    Someone correct me if I'm wrong, but I read somewhere that the temperature reading is for INSIDE the unit and is actually used to compensate for the effects of the temperature on the electronics. It is NOT the air temperature...it is usually higher.

    Anyone know if this is true?

    It is true for Garmin units.
