Lucky you with the waterproof garmin 60C. I have a Garmin Map 12 and it
does not like water. First I learned to seal the socket for the external
antenna. Then I had problems with condensation inside the screen when
the gps was used on top of the spraydeck in sunshine. And last but not
least, the batteries could not stay dry when there was an occational
splash of water on the spraydeck so the gps stopped working. I never
dared to submerge it.



Garmin technical support says (quote):



"The unit is designed to IPX7, but this does not include the battery
compartment. The unit sounds as if it is functioning to specification.
the only thing I can suggest you do to improve matter is to obtain a
waterproof bag for your unit."



There is IPX7 and there is Garmin IPX7.

 I also have the 12 MAP and found that by placing the unit in a baggie, it
was fine. The main problem I found was that with the 12 on the deck, it
would get hot, then a roll would cool it, creating a vacuum and suck in a
few drops of water. I always rinsed out the battery compartment and the
antenna jack after a salt water trip.  Mine did go back to Garmin for a free
replacement due to corrosion of the antenna jack.

The 60 seems to be designed like the 76MAP.

My original Garmin Etrex Legend, started to give me problems when it was
about 6 months old. Garmin repaired the screen, replaced the "click
stick" and did a few other things that were all related to water
contact.

They also told me that although the unit was submersible, the battery
compartment was not. When the unit failed the 2nd time, they told me it
was out of warranty and they could repair it for $125. I opted to buy a
GPSMap76 and I now keep it in a dry bag and tethered to the pocket of my
PFD that it lives in. You just have to remember to not store it inside
the dry bag.

Even though the unit is supposed to float and be submersible, I no
longer trust their statements about water.

My 2 cents,

Steve,

 I have the 76S and find it a great unit and its taken a couple of 
 dunkings without pausing. I've owned several Garmin units and it 
 sounds like you did get a lemon.

They made a number of lemons then. I have a 76S as well, and had it in my
PFD pocket (powered on) and took a spill landing in one-footer's. Wasn't in
deep or long, but the batts were shorted out and were dead 30 mins later.
Lucky the unit wasn't flooded, so new batts and all was OK.  I've taken to
coating the battery compartment mating edges with silicone grease (dive
shops have it) and that has helped. It won't take pressure tho.  I'm about
to cut up an innertube soon.

I'm on my second 76. Never fully submerged the first one, just well 
splashed. It got water inside and died. They sent me a new one and said 
that it shouldn't do that, but after I had an Etrex die inside a 
drybag, I'm not very confident. The problems seem to stem from being 
out in the sun then getting doused with cold water. I doubt the IPX7 
standard tests for this kind of situation. It is one thing to put the 
unit under water for a while in a lab, and another to cook it for a 
while in the sun then dunk it in chilly water.

Doug,

The map76 is that I have is not a lemon. The Etrex Legend I used to have
was. Garmin suggested I keep this unit in a dry bag, and several friends
have had problems with the same unit and saltwater when they didn't use
a bag.

IMHO, the battery compartment is a weak link in their submersability.
Other than that, the unit is great.

Steve
