Technology & me

I like technology but sometime it doesn't like me.  You need a PhD to programme the Garmin watch / computer I wear for triathlon but if you get it right it's excellent for the bike and running.  However it's bulky for the swim and doesn't have the best functionality.
So today I tried out a "pool mate" which is a watch specifically designed for pool swimming.  One of the best features is that is counts your lengths which is really handy, especially if doing a long continuous swim.  This mornings session was 1,500m continuous swim in a 50 m pool.  I decided to try and keep count as I found it difficult to see the lap counter on the screen while moving.  I got to the end and the watch said I had swam 4 more lengths than I thought! Having pressed the reset button I didn't see the time so I'll have to wait till I download the data tonight (assuming I can do that!) to see what the score is.
I'll be gutted if it didn't store the data as it was an important session to time as my coach is looking for these results to see how I am progressing. B****y technology!
