Which GPS is best for me?
robertb...@my-deja.com
in Nuts & Volts Electronic Hobbyiest Magazine 4 years ago regarding the
Trimble Scoutmaster unit. Now there are over 30 units (U.S.A. types).
I have narrowed it down to Garmin GPS 3+, Garmin 12 map, Gamin e-map,
Garmin Streetpilot color (right now, too expensive @ over $700.00). I
am interested in primarily hiking, but specific street/finding address
would be a nice feature. Which units have best satellite locking
(quickest), most accurate, best features for hiking, also possibly good
for car/driving specific addressing. I know the units need 16 Mb
cartridges or flashcards for better car/specific addressing-which is an
added expense. Maybe there are other "european", "japanese" units I
didn't consider. Also looking for one, under $450.00. Is Trimble up
there, as far as good units to consider?
Please help- I'm going to hike in the Allagash Wilderness, (in Maine)
and the heart of Adirondacks (in Ny State) this summer and I am ready
to purchase a unit soon and don't want to make an error in this
purchase.
Which one would you recommend, and or "not recommend"
Thank you,
Robert B

of the 3+ and the 12map are identical(except the 12map has an audible
alarm and the 3+ can switch between horiaontal and vertical display)
The 12map feels better in the hand, can be completely operated with one
hand, is waterproof (specs say submersible for 30 minutes) while the
Emap is not designed for wet weather. My dad has the Emap and it is
great in the car, I have the 12map and it is great in the car as well
plus the boat! The 12map has a trackback feature that would be useful
for hiking as well!
Good luck!

that Garmin put on this unit. It's $20 cheaper, plus Garmin will give a
$50.00 rebate check if you purchase it before April 30, 2000. Im a
little concerned about the "locking feature" for satellite. Does by,
having a "cheaper attenna", make it more difficult for satellites to
lock. The 12map also, has some extra feature (just 2) that the Garmin
GPS 3+ doesn't. What about European , Japanese models?. What
about "Trimble" (What features make it desirable), is it prohibitly
expensive for the "general hiker". I want accuracy, but reliability.
I'll be buying the unit within 3 weeks-so please advise why I should
buy a particular unit.

Who said it was a cheaper antenna?

As far as I can tell it locks just as good and just as quick as the
III Plus.

I will be buying the unit, next week (probably the GPS 12map). I like
the idea that the GPS 12 map is $20.00 cheaper-base price-plus the fact
Garmin will give a $50.00 rebate-if purchased before April 30,2000. But
I did read from one of the "comparitive" articles (I know its not my
imagination), that the GPS 12map was made a little cheaper, and the
antenna was cheaper. If you say that its the "exact antenna"- I'll take
your word for it. Have you had experience with oversea models-my friend
@ "upstate NY", says that there are 12 overseas units "japanese" and I
think "german", that have features better than the american units, work
quicker, lock faster, and might be more "accurate" (I don't see how
possible, if they all rely on the "error routine" 100 meters circle
thrown in by the "Department of Defense")-especially when the whole GPS
unit system is dependent upon U.S. Dept of Defense Satellites (24
satllites now!,-and I think 12 are going to be sent up for more
redundancy and overlap.)
Any information would be helpful.
I'm going be using this (the unit) primarily for hiking (a little
car/direction driving)

The III+ and the 12Map do not use the same antenna but the performance
is
substantially the same. The 12Map is a patch antenna which is prefered
by hikers since it can't easily be broken. It has an external antenna
capability but will not use the same external antenna as a III+.

I don't believe any of this. The maps are different and the Japanese
one
just might display all the text in japanese. Do you read Japanese?

of japanese and German GPS units, and he started "funfering" (excuse
the spelling) (or didn't give a answer). He later stated the units were
used by the military of japan, and might not of been consumer units.
But anyhow, Do you have the spec's on the new Garmin 162 and 168 units
coming out this spring. Should one wait for these unit releases. Whats
the prices?. Whats the specs?. When will they be purchased for first
available date. Are they good for hiking?. I know they have more memory
versus the 12map and Garmin GPS 3+., What other features do these new
units have, compared to the GPS 3+, and GPS 12map?
I will be purchasing the units soon(this week or next), probably (most
likely) from the "Kansas Dealer", whose on this forum. He has the best
prices and best technical support.

(in the Himalayan mountains) where I will both be touring cities and
doing some trekking through the mountains.
What would be the best GPS receiver with these constraints in mind??
*Must be portable and rugged
*Safety: would be best for helping me if I get lost in some out of the
way place!
*Features: best features for traveling in the woods and mountains
*Altitude display and accuracy
*Maps: best maps for cities and towns in Asia
*Computer upload: would be nice if I could store the routes I follow
in my travels, and then upload them to a computer at a later time...
I'd very much appreciate any/all advice!

I assume (always dangerous) the 12 has a 48-type antenna that BNCs on. If
the III+ use the same connection as the II+, the antenna is that slip on
BNC.
If I am correct, it IS a cheap shot. It is not a positive connection and
not as weatherproof. It would be on the level of the slip on F connector on
cable TV.
Basic Ham Radio stuff you already know, though.

All of the 12 models have a built in patch antenna.

component. I have them on many commercial grade radios. They do not just
slip on, there is a push/twist to lock the connector in place...the BNC
is VERY reliable.

the next THREE weeks and now you want to wait till SPRING??? you've only
read good things about the 12map, then buy it.

A full BNC connector has a bayonet locking ring on the male plug, and
the antenna on the GPS 48 uses this.
The GPS II/II+/III/III+ use a different arrangement. The receiver
has a proper female BNC, but the antenna has a male BNC without the
locking ring. When mounted on the GPS, the antenna is locked to
the GPS by a plastic flange on the antenna mating with a groove in
the GPS case.
When you remove the antenna from the GPS, an extension cable will
lock to the female BNC on the GPS - the "ears" for the bayonet ring
are present. But the antenna merely slips into the female BNC on
the other end of the extension cable and is held by friction. There
is no locking ring to hold the antenna to the female BNC. And this
is why you might not want to expose this connection to the airstream
outside a car.
