True enough.

subject: [Paddlewise] GPS Question
Date: Mon, 5 Aug 2002 08:33:40 -0700 (PDT)
I currently have a Magellan M315 and have been fairly
satisfied with it.  It has served well on my sailboat,
in the car, and on the trail.  It does have a few
deficiencies though, especially for kayaking.

  1. It has poor battery life.  On a 1 week cruise I
would need to use quite a few alkaline batteries
(Magellan doesn't recommend rechargeables or at least
didn't at the time I bought it).

  2. It isn't very waterproof.  Mine leaked and was
replaced while it was under warranty.  It is no longer
under warranty so I am especially unlikely to carry it
while paddling without using a waterproof a bag.

Are other brands or models more suitable?  I would
really prefer something with a really waterproof case
and long battery life.  Does such a device exist?

The ability to display maps would be nice but is not a
requirement.  The cost difference probably is enough
to scare me away anyway.  I do keep maps and charts on
my iPaq, but don't use it in the kayak. I might carry
it and use it in camp to plan the day, but using a
waterproof bag and trying to connect the iPaq to the
GPS is probably a bit to much trouble while underway
in a kayak.  It is also likely to result in a dead
iPaq.

Recommendations, observations, or comments?

Pete

Hi Pete,

I myself am using a Garmin eTrex Vista for my kayak and bicycle daytrips.
Although the device is fine, it does not have a terribly long battery life.
It does run about a day on two fully charged 1300 mAh NiMh penlite batteries
(capacities up to 1800 mAh exist and should last longer). The "lesser"
eTrex'es have less features and have longer battery life. In particular the
magnetic compass of the Vista is quite battery-hungry, but fortunately can
be disabled.
NiMh also have the disadvantage of a high self-discharge rate. This is
normally not a problem if you charge them immediately before you use them,
but if you don't trickle charge them and just leave them lying around
they'll be empty in a few months.

The Vista (and most other Garmin units) are advertised as waterproof rated
IPX7 which is immersion to one meter (3 feet) for 30 minutes, but I always
use mine in a watertight Voyageur bag (which makes operating it a bit
troublesome).

Another and perhaps a better choice would be the Garmin 76 or the 76 Map
(I'm tempted to buy one of those as well), as it has a larger display and
floats by itself, and has all buttons up front, so it will be easier to view
and to operate from a watertight bag. I don't know about battery life
though, but information should be on Garmin's website www.garmin.com.
A lot more useful information can be found on www.smallboatgps.com by the
way.

don't get lost,

    Kees

Your 315 should work fine with rechargable batteries although the life
per charge may be somewhat less than with regular alkaline cells. Many
people use NiMH cells in these units, so I'm not sure why Magellan would
recommend against them.

The newer Magellan units (Meridian and Sportrak series) and most Garmins
are rated as waterproof per IPX7 (1 meter for 30 minutes). However, in
many cases this rating doesn't apply to the battery holder and in any
event there have been reports of water intrusion in some samples of just
about every model in the GPS newsgroup (sci.geo.satellite-nav). So I
wouldn't trust any unit without using a waterproof bag. The actual
waterproofness seems to be sample specific - one unit may stand up fine
to repeated rolling while another of the same model may leak from just a
few splashes.

Unless you want to upgrade to a mapping unit, I'd stick with the 315
together with a good waterproof bag (I use an AquaPac).  I prefer to
have a unit which supports detailed maps (I have MetroGuide and Topo
maps for my Garmin). It makes it easy to identify islands and shoreline
features while paddling and can help if there's a need to change trip
plans due to conditions. Garmin's Map76 has more marine-oriented
features than most other units, including tide information, but many
other units such as the Magellan Sportrak or Meridian models or the
Garmin Legend would do as well and are more affordable.
