I think they came out in around 2003-4.

I still have one too but mine is the 201 model. Still works. Just fired it up. One big problem with them was the connection cradle which I had enless trouble wiht. Bad connection for charging and downloads.

There are a few of those buried on the bottom of the speed course at Sandy Point. When we first got them we thought the waterproofing was good enough so we wore them like a watch on our arms. Unfortunately the strap pins could be dislodged in a crash. Later we found they were problematic without using a waterproof bag.

Still got mine but won't start up anymore. An important part of our history as it started the revolution

The above posts remind me of the intro to the Monty Python 4 Yorkshiremen skit
