I noticed on my Forerunner 735XT when my real-time HR drops below 30 the watch displays two dashes as the heart rate next to the heart icon i.e. "- -" instead of a value. A value only appears again when the HR reaches or exceeds 30. Typically when this occurs the RHR is automatically set to 30 and never a value below 30.
See attached photograph where RHR is 30 on S(aturday), S(unday) & M(onday), 34 on T(uesday), 31 on W(ednesday), 33 on T(hursday) and 34 on F(riday).
Call me crazy but I am curious to know what HR value is being detected below 30 as the minimum HR and whether Garmin can calculate and display a RHR below 30.
Has anyone else experienced this on their Garmin? ciq.forums.garmin.com/.../1402323.jpg
