Hi,

I bought an eTrex a couple of month ago.  The waterproofness 
issue was in between also discussed on a usenet GPS group.
Some units were reported (not only eTrex, also XL12 and other Non 
Garmin units) which were not waterproof and died.  According to 
the posters they got replacement no questions asked.  Water 
seems to get in some cases in at the screen window area -Poor 
quality control-.

The fact is, that in almost all handheld units(Garmin, Magellan etc.) 
the same standard is used, i.e. the battery compartment is most of 
the time not waterproof, only the electronic. BTW: Same applies to 
quite a few waterproof VHF radios and their battery trays.

I tested my unit in my bathtub for 30 minutes approx. 30cm deep in 
ice cold water to avoid a surprise in real life.  Result:  the unit was 
and is working, but the battery compartment was dry as the inside 
of the bladder of my hydation pack (reads full of water).  
I doubt that spray water is a problem, I use to carry the GPS in the 
pocket of my PFD -so far always a dry battery tray-, but I would 
expect a swim or a roll to fill up the battery compartment at least 
partly.  Therefore I check the unit after each paddle to avoid the 
discovery of corroded battery contacts one day.  Condensation is 
anotheer reason to do this.
 
However, I will get a small waterproof back for the unit soon -or use 
the condom trick and a piece of foam, because it doesn't float 
(water or no water in the battery tray doesn't matter).
So if an eTrex gets deeper than 3 feet underwater during 
seakayaking it waterproofness doesn't matter anymore -unless you 
do a fast wet exit and go for it.  It will go down to the bottom of the 
sea and if you don't want to loose contact to your boat and paddle 
that's the end of the story.  As far as I know there is one floating 
model from Magellan on the market -that's it.  All others will dive!

The question for me is: What can I expect for 120$ (US)? 
Waterproofness was not one of the reasons for me to get an Etrex. 
And I know that full waterproofness is expensiv to get because it is 
difficult to do if there are knobs, switchs and accessible battery 
containers involved -just looked for a dive lamp :(  , but not to 
recover overboard equipment.  

BUT this shouldn't stop companies to give the full story in their 
adds and not only, if at all, in the small print of the manual or upon 
request.  So it is OK to kick them with this, but don't waste to 
much energy better used for paddling.

My 2 cents
