ULTRASPORT GPS PULSUHR NAVRUN 500
Have just bought one of these as an upgrade to my HRM - it says it's waterproof to 30m BUT in the actual instructions it's not clear if that is just the watch part or the chest strap as well. I want to use this for triathlons so need both parts to be waterproof. All the online help is in German, the Amazon listing isn't…
