If you use a lanyard, make sure it is a good one. I had my GPS fall off into some bushes when we 1st started - off of a lanyard with a cheap plastic clip. Had a hard time finding it, even though I knew where it fell off. It was then that I bought a red faceplate for my GPS and a case. On that note, the case had a built-in belt clip. I used it for 1 week. Went to a caching event, and while in search of one of the caches, the 3-yr-old got tired. While carrying her, she kicked it off. Glad I had the red faceplate! Made finding it easier. Now I have it on a sturdy lanyard, and haven't lost it since.
