I use a garmin foretrex 201 , but as Jake has found to cost don't rely on pins !!!!, first time out I lost one and nearly the unit , a friend lost hers first time - both pins came out , and another two folk in my club have lost pins very quickly , all now strap to boat with tape around unit itself , I sometimes use a neoprene arm band with mylar window intended for a mp3 player which does the job , buttons can still be pressed through neoprene.

I told Garmin about their "serious " design flaw and offered the neoprene arm band solution, they didn't seem too concerned though,as they didn't consider it a problem , they offered to replace my unit which I accepted but its no different , my friend who lost hers completely was given a new one too .

A while back some brave soul brought this matter to attention on Yachts and yachtings website in UK , but the thread was removed by Y & Y and soul dissapeared into ether , perhaps as Garmin advertise with Y & Y !

or am I being sceptical ??? !

If anyone has a 201 and loses pins let Garmin know , perhaps they wil then recognise this flaw in an otherwise great unit.
