Hello,
Recently, when I used manually created course in Garmin Explore in Trail Run activity I noticed that information about leaving course and then being back at the course was way too often. There is not enough precision to create course as it is in reality but still I can see I'm generally at the real track. But Garmin Instinct was buzzing and beeping very often which is pretty distracting. I know I can disable this alarm but I find it useful. I've got suggestion to put to soft additional option for this alarm to customize threshold for it. For now it looks that threshold is around 5-10m max then alarm is triggered.
Regards Rafal
