~ I got sick and tired of rubbing spit on my chest strap, and waiting outside in the cold in my shorts while my watch tried to find my heart rate monitor. A friend lent me his Sync Gel and I've been using it ever since. My HRM syncs the moment I put on my strap. No Waiting. Thanks
~ For me my HR monitors connectivity was particularly bad, as my chest is rather on the hairy side :). A little bit of Sync Gel, and my HR strap syncs immediately.
