I used both models of geovids for years. I have not used the newest HD-b's. frankly the geovid glass was nothing to get particularly excited about. comparing it to the victory isn't accurate. I would say even the old first generation EL's were better. probably comparable to trinovids from 12 years ago. YES having lesser glass with a RF is still way worth it though.
if your looking on the used market there is a step up from the geovid to the geovid HD's. the RF function is about the same between those 2. basically plan on ranging to 800 ish on big game size animals. that will probably take several tries to get that BTW. Yes it can range further in certain conditions. you may need several tries to pull a range on big game animals over 500 yards.
