It's really a great review you have made,my question is if you can make a video of Pentax PF 100 ED ?? How it is and as Pentax says it has Lanthanum crown rare earth glass and performance is similar to Kowa Zeiss and Swarovski but i didn't find a chance to look through it so please make a video of Pentax PF 100 ED spotting scope

I just received the Vanguard Endeavor HD 82A, I can honestly say, my unit punches wayyy harder than the price suggests. The glass is very clear even through 60x. The focus knob for rough and fine focus works absolutely suburb. I also tried it in low lighting and at dusk and was still able to get an acceptable image. I am truly pleased with it. I considered scopes well over $1k including the Tract TORIC UHD 27-55x80, Maven S1A, and the Vortex Viper HD or Vortex Razor HD. However I couldn't justify spending that for my first spotter. I am sure the glass quality is much higher in the Tract and Maven than this however the clarity through the magnification is what I am impressed with at this price. I would put money on this that this could stack up with the Vortex Viper HD if all units preformed this well. I would highly recommend this. The warranty also sounds pretty legit as well. Overall it's nice not having to spend $900-$1000 for something with similar quality. Just my 2 cents. Cheers!

Great review; been looking for a thorough side by side comparison of a couple of these scopes and this covered all the bases. Any insight on how the Maven CS1 compares to the full size Vortex Razor 65mm?

you didn't focus as well as possible. go to around 20:40. 1000 vs 800 vs 300.....best value is 300
