Picture of Garmin eTrex super cheap screen guard
In this instructable I show you how to make a super cheap screen guard for the eTrex. This not only protects the screen but the entire unit while still allowing you to operate it. Also since it is entirely transparent it doesn't spoil the look.

While the eTrex unit is quite rugged, my biggest fear has always been of the screen getting scratched. Also I noticed that if you use a handle bar mount (see my other instructable) like the one I made, vibrations may cause the mount to rub against the body of the eTrex and cause scratch marks. ( I like my gadgets new and shiny :-) )

Step 1: The Materials

Picture of The Materials
1. A plastic bottle of your favourite drink
2. A scissor

I used a 1.5Litre bottle of Coke as shown in the picture, the important thing to remember here is that the circumference of the bottle (measured around the lable) should be identical to the circumference of the eTrex measured along the length/vertically.

This will be more clear as we go along once you understand what it is I am trying to do....

Hope you have finished drinking that bottle by now because you need to empty it, wash it and dry it for the next step. Burp...

Step 2: Preparing the bottle

Empty, wash and dry the bottle, then remove the lable from the bottle.
Now poke the scissor into the bottle carefully and start cutting it so that you are left with the transparent cylindrical portion of the bottle as shown in the picture.

Since I don't yet have a good camera and the bottle is transparent anyway, I will try and explain with the help of hand drawn diagrams.

Step 3: Putting it together

Now squeeze the cylinder as shown in the picture to flatten it. Don't flatten it too much to create a fold just yet, but just enough for the etrex to slide in. In my case I found that I had to push the etrex in with a bit of force since it was a proper fit.

It works better then the cellophane screen covers for the games. It can take a lickin, and be cheaply replaced.

On my yellow etrex, the glue became gooey, and the power button tore. I repaired both using silicone caulking. I removd the glue using white spirit I think. Nothing to do with the screen protector, but maybe worth mentioning.
That is good advice. It seems to be a common problem with those. Thanks.

I went to Radio Shack and got the portable play station screen cover and cut it to fit the screen. You can get two from one package, also work good on cell phones

It would be good if you could post a picture.

Does this mean you have a camera, albeit a lousy one? If so, I would recommend taking pictures and posting them alongside the diagrams.

Also, since you apparently have an eTrex, I'll just ask you straight off: can the eTrex display your coordinates, does it use decimals or degrees, minutes, ad seconds, and how many decimal places/ seconds does it go to? I've seen plenty of images of the eTrex screen, but none show coordinates. I just want a GPS that will show me where I am, but no one advertises, "The CameronSS GPS--shows where you are, and nothing else!"

There's an easier way: packing tape. Packing tape is the perfect width for my Garmin 76csx screen. Just cut to length and you're done. And it's clear and strong. I've had tape on my screen since Jan 2007. It hasn't loosened or scratched.
Oh yeah. Trim with a razor blade if your screen is smaller.

Very clever. My Garmin GPS is a bit larger, but I may get lucky using a 2 liter bottle.
