Brian, how was the camera versus the camera used on the VS485c (which is the HADII CCD sony camera)? Where I fish, it’s stained, dirty water and camera quality is more important than direction.
Doc I replied to your post. If you would get your boat out of mothballs you could see for yourself. 
“video lag”
Looks more like it skipping a split second of recording to me.
Check your Micro SD card. I shouldn’t be over 32 gig and have a “10” with a circle around it. Less then the ten, the data transfers slower.
As mentioned earlier some place, I’ll be using mine this weekend and it will be interesting to see if there’s any skipping or lag.
