    RE: PDA/GPS unit recommendations

    Hi All,

    We had some recent interest within the chapter for increasing our use of
    GPS
    receivers and PDAs to gather mapping data in the field using ArcPad. I'm
    curious to hear what other chapter's experiences have been with various
    recent models of either and if any of you have had any hands on experience
    with using an integrated unit (PDA with GPS): likes, dislikes,
    compatibilities and incompatibilities, expense, etc.

    Thanks!
    Steve

    RE: PDA/GPS unit recommendations

    I did a lot of this for my last job, and I recommend Dell Axims with a
    CF-GPS. Axims are cheap, have a CF slot for the GPS, and a SD slot for
    memory, and they're pretty reliable. I've had bad experiences with iPAQs,
    which I think tend to be overpriced and include a lot of useless features
    for this particular need. Bluetooth GPS can work OK, but again I've had
    trouble with some models, and the power drain is higher with wireless on.
    I
    settled on the teletype CF-GPS as my favorite when working with ArcPad.
    I've set up maybe 7 different models with various configurations of
    PocketPC
    and GPS, and the Axim/Teletype-CF combo is my favorite for the cost. You
    can get an Axim X51 for $300, add a $250 GPS, and spend maybe $60 on a 1GB
    SD card if you have a ton of image data to display (or get a smaller
    cheaper
    one otherwise).

    Hi Jon,

    Thanks for the great information. We've been leaning a bit towards iPaqs
    and
    taking a wireless approach based on the experience of staff within our
    Heritage program in Michigan. However, it's great to hear your success with
    the Dell alternative. Do you have a preferred GPS receiver (we're currently
    leaning towards some model of Garmin) and what's your typical battery life
    with the Axim?

    Again, many, many thanks for your input and have a great weekend!

    Cheers,
    Steve

    RE: PDA/GPS unit recommendations

    Steve,

    We've had decent success with Dell Axim PDAs and EMTAC Trine bluetooth GPS
    receivers. I don't know if this is also the case with other PDA models, but
    one problem with our Dells is you have to keep them charged regularly. If
    they sit for a few weeks without being charged, the batteries can get
    completely drained and data and programs you've installed (like ArcPad)
    will
    be lost. They also don't have the greatest battery life - we only get 3
    hours at best from one battery so we've bought spares.

    Also, if you're going with a standard, non-rugged PDA, Otterbox field cases
    are a must (http://www.otterbox.com/).

    cheers,
    Chris

    RE: PDA/GPS unit recommendations

    Hi Steve-

    We've had experience in Idaho with iPaqs, Axims, the Trimble GeoXT
    units, and the Garmin iQue M5. Of course the Trimble is the Cadillac of
    the bunch, but it'll cost you an arm and a leg. My favorite alternative
    at the moment is the Garmin iQue M5 because it integrates that PDA and
    the GPS unit (and it's a whole lot cheaper than a Trimble). I haven't
    run into any major problems running ArcPad on the Garmin iQue, but you
    might want to research this some to see if other people have run into
    issues. We have also had a number of GPS devices for our PDAs. We have
    three of the Navman jacket-style GPS units for iPaqs that have worked
    well, but last year, one of them mysteriously gave up the ghost. In
    terms of CF-card GPS units, I've had very mixed results. Our first CF
    GPS was a Pharos. It worked with ArcPad, but was notorious for losing
    its fix and giving locations that were significantly off compared to
    other GPS units being used simultaneously. The next CF GPS unit that we
    got was an EMTAC (distributed by Transplant) because it had received
    good reviews. The problem we ran into with that was that our Axim's or
    iPaq h2215's couldn't access it over the COM port that was assigned to
    the built-in CF slot. If you plugged it into a GPS CF-jacket for an
    older iPAQ, it worked beautifully. Our latest venture was a Garmin CF
    GPS unit. We opted for the Garmin because we had had good luck with the
    iQue M5 units and figured that Garmin was a reputable brand. The CF GPS
    units works great with Garmin's navigation software, but since it
    doesn't output NMEA sentences (uses Garmin proprietary format), it can't
    be used with ArcPad (I don't remember seeing the fact that it doesn't
    export NMEA on the spec sheet, but it could just be that I was being
    dense [again] when we were looking at it). So my number one caution to
    you would be to make sure that the CF Gps unit you get will export in a
    format that ArcPad can handle. My PDA/GPS setup is a Dell Axim 3Xi with
    an EMTAC bluetooth GPS. Whereas I really love the bluetooth wireless
    setup, a couple of the field users that I've lent it to have had
    difficulties in making the connection to the bluetooth unit before you
    can activate it in ArcPad. Just something to think about if you're
    dealing with users that aren't really tech-savy.

    In all this hassle with PDAs and GPS units, I'm actually coming back
    around to using a stand-alone GPS unit cabled into the PDA. That
    generally gives you the maximum battery life as the GPS isn't sucking
    juice off of your PDA, and also allows you to continue to use the GPS
    when you get a new PDA. I know the cabling can be messy and less than
    ideal in the field, but there are a number of companies out there that
    are selling custom-cut cables to interface many popular GPS units
    (mostly Garmins) with specific brands/models of PDAs.

    Give me a call if you want/need more specifics on any of my ramblings...

    RE: PDA/GPS unit recommendations

    Funny, I had the opposite problem. My iPAQ would lose 20% of it's charge
    in
    a few days of being powered off in a drawer, I've had Axims sit for several
    months without being charged and still be fine. Though using ActiveSync's
    Backup feature is a good idea anyway just in case. The iPAQ cost almost
    double what the Axim did, partly b/c it had WiFI technology that has little
    application to most field work (whereas I got the stripped down Axim).

    Regardless of the model you go with, I think it's worth the money to get
    the
    extended life battery, and keep the original as a backup that you can swap
    out in the field. I know Axims can have the battery switched without being
    pluged in (they have a backup battery), and some models don't, but I'm not
    sure about iPAQs.

    I definitely agree that the Pharos CF-GPS is terrible, I only got it to
    work
    with the extra antenna plugged in and it was still marginal. The Teletype
    CF-GPS, however, has been very easy to use and reliable for me. It does
    pull power from the PDA (as opposed to separate batteries), but it's fairly
    low power consumption so I found that it wasn't much worse than the drain
    of
    having Bluetooth on. One disadvantage of the CF-GPS is that they won't fit
    a standard ($50) otterbox, you need to go for the $100 model if you want a
    floatable, waterproof, dustproof, non-crushable unit. Alternatively, you
    can buy a waterproof sealable bag for around $25 and just be careful not to
    drop it (this worked well enough for me).

    In the event you go with Axims and a CF-GPS, I have a checklist of steps to
    go through for installation to get everything working properly, and how to
    make backups, etc.

    RE: PDA/GPS unit recommendations

    We have a Dell Axim, which is a great PDA but doesn't hold a charge all
    that
    well. For the GPS we have an EMTAC bluetooth. I personally would rather
    have a CF unit, as having the bluetooth GPS creates two potential points
    for
    signal loss... one being between the GPS receiver and the satellite, and
    the
    other being between the GPS unit and the PDA.

    So, I would recommend the Axim, but NOT recommend the Emtac.

    Funny, I had the opposite problem. My iPAQ would lose 20% of it's charge
    in
    a few days of being powered off in a drawer, I've had Axims sit for several
    months without being charged and still be fine. Though using ActiveSync's
    Backup feature is a good idea anyway just in case. The iPAQ cost almost
    double what the Axim did, partly b/c it had WiFI technology that has little
    application to most field work (whereas I got the stripped down Axim).

    Regardless of the model you go with, I think it's worth the money to get
    the
    extended life battery, and keep the original as a backup that you can swap
    out in the field. I know Axims can have the battery switched without being
    pluged in (they have a backup battery), and some models don't, but I'm not
    sure about iPAQs.

    I definitely agree that the Pharos CF-GPS is terrible, I only got it to
    work
    with the extra antenna plugged in and it was still marginal. The Teletype
    CF-GPS, however, has been very easy to use and reliable for me. It does
    pull power from the PDA (as opposed to separate batteries), but it's fairly
    low power consumption so I found that it wasn't much worse than the drain
    of
    having Bluetooth on. One disadvantage of the CF-GPS is that they won't fit
    a standard ($50) otterbox, you need to go for the $100 model if you want a
    floatable, waterproof, dustproof, non-crushable unit. Alternatively, you
    can buy a waterproof sealable bag for around $25 and just be careful not to
    drop it (this worked well enough for me).

    In the event you go with Axims and a CF-GPS, I have a checklist of steps to
    go through for installation to get everything working properly, and how to
    make backups, etc.

    Steve,

    We've had decent success with Dell Axim PDAs and EMTAC Trine bluetooth GPS
    receivers. I don't know if this is also the case with other PDA models, but
    one problem with our Dells is you have to keep them charged regularly. If
    they sit for a few weeks without being charged, the batteries can get
    completely drained and data and programs you've installed (like ArcPad)
    will
    be lost. They also don't have the greatest battery life - we only get 3
    hours at best from one battery so we've bought spares.

    Also, if you're going with a standard, non-rugged PDA, Otterbox field cases
    are a must (http://www.otterbox.com/).

    cheers,
    Chris

    Hi All,

    We had some recent interest within the chapter for increasing our use of
    GPS
    receivers and PDAs to gather mapping data in the field using ArcPad. I'm
    curious to hear what other chapter's experiences have been with various
    recent models of either and if any of you have had any hands on experience
    with using an integrated unit (PDA with GPS): likes, dislikes,
    compatibilities and incompatibilities, expense, etc.

    Thanks!

    RE: PDA/GPS unit recommendations

    I have a personal PDA/CF-GPS combo that works pretty well for me. It's a
    Dell Axim with a Syson Memory GPS. This model has the added benefit of 256
    (or 512) Megs of storage space to hold data.
    It uses Xtrac2 which from my research and experience works well under leaf
    cover. I was under the impression that the accuracy of these CF units were
    comparable, but I've got nothing to compare mine to. There does seem to be
    a
    considerable amount of error as I can often watch my position drift around
    the map as I sit in one place. At it's worst it can be off by 100'. What
    kind of error are all of you seeing in the field?
    My Axim is the 400MHz x5 and was often slow to load data, this has improved
    quite a bit since I started using a demo of ArcPad 7.

    -Kevin

    RE: PDA/GPS unit recommendations

    The Oregon program primarily uses Dell Axims (X5 and X50), and we seem to
    have really good luck with battery life as long as we use the 'enhanced
    life' battery. We started with the Pharos CF GPS units, and found similar
    problems with keeping a fix reported by others. Other than that, it's been
    mostly the Holux GM-270 and the GM-270 Ultra. The former is WAAS capable,
    but the latter is not, which is a disappointment. It has XTrac2, which
    increases sensitivity, but also appears to create a lag in updating the
    current position. This causes the position indicator to jump in ArcPad,
    which can make it difficult to relocate points. Some staff have also noted
    occassional inaccuracies with the Holux Ultra when comparing it different
    Garmin GPS units. We now have a GlobalSat BC-337, which is WAAS capable
    and
    appears to be very sensitive (I can get a fix indoors, though I don't know
    how accurate it is), but we have not field tested this yet.
