Emilio Trampuz wrote a question about Casio Pro Trek PRG550-1A1 Altimeter Watch on November 25, 2012
Are any of the Casio watches good for recording the vertical skied? If measurements are taken only once every 2 minutes, a lot of vertical may not be recorded. Also, it seems there is no way to have the altitude changes recorded all day long, because there is no start/stop button. Every time I need to check the time, or the compass, the altimeter is automatically stopped. Is that really so?
