It's taken me a while but I've now acquired a replacement for the Casio Protrek triple sensor. I liked most of the functions of the Protrek but I just found it too big and bulky. Anyway, after looking around for a while, I've picked up a Pulsar PS7001. It has temperature and altitude but it doesn't have the compass that the Protrek had. Not that I ever used the compass and you had to keep calibrating it far too often for my liking. Anyway, here's a picture of the new watch in the collection.
