My heart rate reading drops to 49-50bpm when out for a long walk which is way below my resting heart rate of 65. Why would it simply drop so low when I know it was reading 90-100 bpm earlier in the same walk??

It could be that it locks to your cadence during some section of a walk, wrist-based OHR sensors have this issue.
I have found on a rare occasion that the HR appears to be half what I would expect and have assumed that it has locked onto the stronger (systolic) beat - as if it can't believe I'm working so hard! ;-)
Same issue. I took a hike up a mountain today. I could hear my heartbeat and counted it as about 140. Its not that I'm in bad shape, just old. The brand new Instinct (all software up to date ) reported between 60 and 70. I thought of the same explanation, but not a reason for it.
Because of this I am using chest strap hr sensor from old polar, way more accurate.
