Handheld GPS - Tool or Toy?
Story by Paul Crawford
Every year about this time, we see a steady
stream of questions from folks just entering the GPS market for the first time.
There is plenty of room for confusion with various advertising claims, endless
options, add-ons, all piled on the basic magic of having a satellite 11,000
miles above the earth lead you by the hand to that secret sunken brush pile or
the next Pizza Hut down the road.
A natural tendency related to financial
self-preservation is to just try and dip your toe in this cold water first, so
we see a lot of questions about getting a handheld GPS to start with, then we'll
look at the bigger, more expensive units later.
With all of the advances the last few years in
handheld units, it certainly seems like a reasonable course of action. However,
the Electronic Revolution of late has brought us not only very capable handheld
units, but very affordable console units as well. What is a newbie to do? Go
with the handheld or risk buying a console unit that they will outgrow in a
season? It's gotten to the point where it confuses me, so I can only imagine
what a new user is faced with.
I got in early on the GPS scene so I was used to
big bulky expensive gear and I am duly impressed with today's modern marvels.
While following the manufacturers claims and dockside banter about handheld
units, I was at once impressed, confused, and rather irritated at the mix of
claims, experiences, and in too many cases, misinformation presented on the
mighty mites. However, I couldn't really challenge over-the-top claims because I
had to admit to never owning a handheld unit. Now GPS units number among many
things that irritate me at this stage of life, and I'd probably have just left
them on the "minor annoyance" pile had not my wife produced a
newspaper ad about combination GPS units / MP3 players with some not so subtle
hints that we should soon invest in new technology. It was time for me to
investigate the facts and fiction of handheld units and find out for myself
whether they were a useful tool or just one more hi-tech toy to buy and be
disappointed with.
I made a call to my friends at Lowrance
Electronics. I'd reviewed several of their units in the past and liked them
enough to buy them for my own boat. (Yes, outdoor writers do occasionally have
to buy products.) Looking through their catalog, I asked them to lend me one of
their iFINDER® ® units for a product review and extended field test. I sensed
this request rather caught them off guard since outdoor writers as a rule always
ask for the latest, greatest, and most exotic units. After some convincing that
I was serious about a real world test, they were kind enough to send me the very
unit my wife was looking at, the iFINDER® PHD.
The iFINDER® PHD is an excellent example of the
high end multipurpose handheld units of today. It is a mapping GPS that has the
additional map-making software for your PC. The PHD also has the capacity for
removable MultiMedia Cards (MMCs) to transfer maps and data between your PC and
the unit. It will also accept aftermarket maps from Lowrance, LakeMaster,
Fishing Hot Spots or Navionics. Lowrance also offers hundreds of lake contour
maps for free download from the web site www.lowrance.com. In addition, it has a
built-in MP3 player so you can take your tunes with you. Since I wanted to try
this baby out as my only GPS for the test, I also needed a way to mount it. So,
I ordered the optional RAM® mounting kit. No sooner had the stuff arrived, then
I was ready to give it a try.
I had several questions I wanted answered over
and above, "Does this thing work?" I wanted to know how well do
handheld units acquire their signals? I wanted to know if I could mount it
secure enough in the boat to use it while on the move? For that matter, my wife
wanted to mount it in her truck and find her way to the grocery store with the
thing, (too many TV commercials.) I wanted to know if the aftermarket fishing
maps worked? She wanted to know if her MP3 Audio Books would work? I wanted to
make some new maps, she wanted to use them. I was interested in some of the
advanced features, she wanted the most basic usage as a new user. Could one
relatively inexpensive unit do it all?
So, does this thing work? I expected that any GPS
unit would be accurate and indeed that remains true. The GPS system timing, and
thus accuracy is a function of the satellite signals, not the chip set in the
unit. You do get different accuracies with units that see different numbers of
satellites, but with error correction if your unit can "see" and
utilize 5 birds (satellites), then all GPS units' accuracy will be the same
regardless of model.
This immediately brings us to how well the
handheld units can actually see the satellites and how long does it take them to
"acquire" or use them? Turns out that is another pleasant surprise.
The iFINDER® acquired the signals in a very reasonable time and could do so
under some surprising conditions. Picking up the weak signals from the
satellites has always been a little bit of a trick. There are a lot of things
that can get in the way or cause errors in the signal. The satellite clocks have
a little error in them, the orbits aren't exact, the atmosphere causes a few
problems, and the signal can bounce around the ground off of various surrounding
objects similar to ghosting on your TV set. Add all of this stuff up and it's a
wonder we get any signal at all. That makes it all the more surprising that you
can lock on while traveling inside your car, or even sitting in a chair in your
living room, (actually did it!) Now, if you look at the signal page, you'll see
that the unit is switching between birds all of the time but the location
accuracy appears steady to the user, (all of the switching is invisible.) The
console mounted units we use in our boats usually don't have to worry as much
about overhead interference or multi-path errors from surrounding structures.
Overall. you have to take your hat off to how well the handheld can ferret out a
signal.
Now that we knew the thing worked, it came time
to find a way to mount it in my boat. The RAM mount system has been around for
years but I had never bothered with it before. I got several styles of bases to
try. The easiest and therefore the first was a suction cup design. The idea is
to find a nice flat space and pull a vacuum with the suction cup, thus securing
everything at your choice of flat areas. Of course the first observation is
there are very few flat areas in a modern boat. Assuming you find one and clean
it sufficiently to get a suction, then the base will indeed stay fairly secure.
Unfortunately that security did not survive mounting the unit on the base's
swivel arm. Try as I might, I could never get the base to stay stuck with the
weight of the unit pulling any leverage at all. Now someone might get the thing
to work, but I wouldn't trust the cup to keep my unit aboard a bouncing boat.
Much better results were had when I switched to a fixed mount. I found a little
hidden space where I was willing to drive in a screw and mounted the unit on a
long swivel arm. Now that mount was impressive. Even when plowing through big
whitecaps, the mount kept the unit secure and in place. I was getting tossed
around the boat but the mounting arm never budged or sagged. The whole mount
would vibrate a bit but it never slipped out of my chosen adjustment. And as
tight as it held the unit, a simple twist of the adjustment lever and it would
easily swing to any new position. If you're not going to dash mount your unit,
the RAM mount proved to be the way to go. This one I'd trust to keep the unit
aboard.
Mounting the unit in the wife's truck encountered
similar problems as with the boat. The suction cup mount requires a smooth
surface, something we couldn't find in her cab, although I have to admit I never
tried the windshield. Since she refused my offer to drill a few holes in her
dash, we propped the GPS unit up against the window or in the cup holder of her
console. If you're a little more intent on mounting the unit, I'm sure you could
find a hidden spot that would work in most vehicles without cosmetic damage. My
wife just didn't care enough to prove it.
The mounting of the unit was only the first in a
succession of disappointments for my wife. She suffered the very typical problem
of overblown expectations. She had seen one too many TV commercials for
voice-directed GPS units in her car and was devastated to find out it didn't
work that way. First was the matter of the interface. About the only thing
obviously useful for her about the controls was the Zoom In and Zoom Out
buttons. The power saver mode that comes as a default setting had her convinced
she broke the thing. The menus, while well organized for the experienced user,
just added to her confusion and frustration. Even if the PHD had an Easy Mode,
(couldn't find one in the manual), the wife would have never given it a chance.
After the fascination of watching the map move as she rode along wore off, so
did her interest in learning to use it. There was trouble in paradise.
Next up was the mapping software. I told the wife
that we could add detailed maps to the unit and it would show her where
interesting businesses or highway exits were located. She was willing to give it
another chance and spent some quality time with the documentation. But in the
end, her unrealistic expectations got the best of her again. I programmed up the
local area with some points of interest from the MapCreate™ software. We had
detailed street names, gas stations, exits, and several other things I deemed
worthwhile all displayed on the unit. She started out using some very unladylike
language about the search function interface, but I thought she just needed some
time. The end came abruptly when we had maps that showed exactly where the point
of interest was, but didn't plot out the street names of how to get there. She
just couldn't get over that the GPS unit was not going to be Map Quest in a
bottle for her. I was awarded custody of the unit along with storage location
suggestions while my wife went off to find the Tom-Tom internet site. Now I
seriously considered around that time to call up Lowrance and talk to them about
their iWAY™ units that I had heard so much about and thought was exactly what
the wife wanted. Then, I wondered aloud just why I'd want to switch from fishing
to driving products, give up the opportunity to have endless playtime with the
iFINDER and an excellent excuse for uncontested boat time to conduct the test.
Upon further reflection, I decided to not only let sleeping dogs lie, but leave
quietly as to not arouse them on the way to the lake. So much for the driving
tests.
Long story short, if you're looking for a highway
driving aid to tool around town, the iFINDER is probably not the best unit for
that.
I think we also uncovered a "new user"
flaw for an inexperienced user. That is, the full capability that's built into
the iFINDER lets you do anything with the handheld you can do with a bigger
unit. In fact, as near as I can tell they actually run the same software,
sharing menus, functions, and interface. All of this power is bound to cause an
introductory problem. A simple quick start user's guide to go along with the
reference manual could go a long ways toward relieving the frustration. Short of
that, I'd recommend any new user to curl up with the manual and perhaps download
the free on-line emulator from the Lowrance website. In spite of what they might
say, instant gratification is not a hallmark of consumer electronics in the
Information Age.
Now that I had sole possession, it was time to
put this thing to work! I wasn't interested in how the unit worked in town. I
wanted to know how it worked on the water. Exit the street maps, enter the lake
maps. Since the iFINDER® will only take one card at a time, I came upon an old
problem. The commercially available lake contour maps come on their own memory
cards. While it is possible to add street maps you're risking corrupting you
precious contour maps if you blow the memory limits. So, you're left with a
choice, do I load up the lake or the road to it? The stock answer from the
designers is that you're supposed to have both cards and switch between them
when you get to the water. My realistic outlook is that I've already lost one
mapping card in transit and changing cards is a pain in the patoot. This goes
double for the iFINDER® since they tucked the card slot inside the water
resistant battery box, of course below the batteries. Switching between cards
will work, but the pain level is just too high for me.
Now the really good news is the memory cards are
the same between the iFINDER® and the console units. This opens up my favorite
use for the iFINDER® , taking it with me to someone else's boat. What once
began as article research became standard gear for me. On those occasions I
become a passenger, I always find room to pack the iFINDER® . This gives me at
least two advantages. First, being able to lead us to my offshore honey holes,
Second, capturing the GPS coordinates of new spots that my partners are willing
to share. Without a doubt, that capability alone is worth the price of
admission. If you're someone who has a library of plots and trails you've saved
up from one of the big combination units in your boat, then you'll be pleased to
know they plug and play with the handhelds. This makes the iFINDER® the perfect
complement to your bigger rig and a secret weapon for draw tournaments. At the
very least, it stopped a lot of the arguments over who's boat we ought to take.
If I'm fishing my own water I don't care that much which end of the boat I'm
fishing from.
The memory cards aren't limited to maps with the
PHD but offer your own private juke box as well. The basic idea I wanted to try
out was to load audio books on the unit. The memory was certainly large enough
to hold book chapters and it seemed an excellent replacement for the wife's CD
player, discs, cords, and other paraphernalia that routinely travels with her on
a day's fishing trip. Just a couple of things spoiled this plan. First is that
card switching thing that meant when we got to the fishing spot, I had to remove
the batteries, load up the new card, and then yield the GPS to my wife instead
of monitoring my position. Okay, life is full of compromises. The second thing
isn't a fault of the unit at all, but of the nature of MP3 players. It turns out
not all MP3 files are created equal. One of the very unequal file types was the
one my wife subscribed to on her web service. They just didn't fit the standard
format. We both agree that listening to a book on the PHD would be a nice
alternative to the CDs if the audio source supplier distributes in a more
standard format. As it is, the PHD was reduced to music and other audio clips,
albeit with very good sound quality and a good user interface. Even with the
capability, given the bother of switching cards on the water, I'd still prefer
to buy the wife her own MP3 player and keep my GPS for monitoring our drift
while we're fishing.
The one real complaint I had trying to use the
handheld unit for monitoring drift, course, or anything else is the obvious
limitation you have with small screen size. The display is actually quite good
for its size, but you can't change the fact it is small. If you're holding the
unit in your hand, reading the display isn't too bad if you get the bifocals at
the right angle. When you start mounting the unit in one of those out-of-the-way
spots, there is no right angle. Simply put, every time I left the unit in its
mount it was too far away to comfortably read. The detailed contours on the lake
maps just made matters worse by providing enough background clutter to obscure
any current path information. Add some vibration from running across choppy
water and you're left somewhere between a hint and a guess of where you're at.
Now if you're holding the unit, you can see just fine even while running. It's
just a little awkward trying to steer a boat jumping whitecaps with one hand and
hold a GPS in the other. I suspect the visibility would be dramatically improved
with a color display, something the PHD lacks. Still, small screens are, well,
small and that does limit what you're going to do from a distance.
Night time viewing is excellent, at least once
you figure out how to keep the back light on. The default power settings turn
off the back light after a few seconds to save batteries but you can modify that
default from a menu. You can change the contrast and light level in order to
yield an excellent night time display. Just one more example of why I like
Lowrance screens and graphics.
So, what's our verdict? I'd give it a solid
"B" for useful tool and a rather weak "C" for toy. The large
capability interface and learning curve makes just playing around too
intimidating for a new or casual user. The MP3 capability is good but the
reality of switching out the cards behind the batteries limits the fun. As a
primary unit for guiding your boat it has all of the capabilities but small
screen size limits the presentation of the information. The MapCreate street
maps and points of interest work for the experienced user but it's not a
substitute for a turn-by-turn routing product. As an auxiliary unit to pair up
with a bigger console unit as a traveling companion, it's A+ all of the way. It
held up wonderfully over a season of beatings, and being dropped a few times,
knocked off a table by the cat, and a couple of rain storms.
I'm going to ask my wife to get me a new console
unit for the boat and an iFINDER® to go with it for my next birthday. I'm going
to get her an iPod.
Until next time, have fun and stay safe.
