I also have the Pulsar Quantum HD19A. Loved this until the warranty ran out & started having issues with it sent back to Sellmark twice to get it fixed as I have to reconfigure it manually about every 5 minutes. Cost me $$ in shipping with it returned unfixed both times 
( I WOULD HAVE BOUGHT ANOTHER IF THEY WERE STILL MAKING THEM )
With that being said I’m using it again now as my grandson has been scanning with me lately.
This is what I use now BUT I preferred the HD19A field of view ! Go with the lowest magnification for a scanner guys !!
Pulsar Axion 2 XQ35 LRF 2-8 thermal monocular. I do like the LRF & PIP option ! I never move it off 2, that’s what my scope is for.
