I haven’t read every post here, but I will share this as a reference:
I bought a Simmons Blazer 20-60x spotting scope for $60 at Walmart around 15yrs ago while on a prairie dog hunt in Nebraska because I had forgotten to pack my Leupold Ventana. I used it on that trip and several other occasions over the years. For the money, it did more than expected, but it was a known source of headaches, and a sincere letdown in terms of spotting anything beyond 300yrds at all, and certainly limited bullet hole witness to 100yrds. The Ventana was not a top tier spotter, but it was about 10x more expensive than the Simmons.
Then several years ago I bought a Bushnell Elite 20-60x, which was running $1600-1800 street price at the time. What the Ventana was over the Simmons, the Bushnell was over the Ventana, but the price only tripled between them (not 10x). I also have a Bushnell 15-45x Elite Tactical (T Series compact), which isn’t quite what the Elite cost, actually about equal to the Ventana when I bought both. For the money, the T Series was as clear on target as the Ventana, despite being a 45x, rather than a 60x.
So then early last year I picked up a screaming steal on Swarovski SLC 15x binos, and immediately replaced my big Bushnell as my primary spotting tool for precision Rifle matches.
Comparably (using the original street prices of all of these), the $600 Ventana was more clear at 600 than the $60 Simmons at 300, the $600 T Series could see as well at 600 while on 45x as the Ventana could at 60x, and the $1600 Big Bushnell could see as well at 1,000 as these others at 600. But the $2500 Swaro binos has better image at fixed 15x than the big Bushnell can at 60x. You might imagine, looking through the Simmons beside the Swarovski’s establishes a spectrum of “nearly blind” to “perfect image”.
Similarly - I killed dozens of deer with a Tasco World Class 4-16x on top of my old 30-06, which I paid $350 for WITH a Ruger M77 MkII over 20yrs ago (not a used package - used rifle + new scope). I have a $900 Sig Tango4 4-16x on it now, which is every bit better than the $200 Tasco was, in every lighting condition. The Sig, however, doesn’t keep up with the Bushnell 3.5-21x DMR II for image quality and light transmission. It also cost less than half as much. I have a Nightforce ATACR 7-35x on my new match rifle, and it’s everything above the Bushnell that the Bushnell was above the Sig. Like the spotting solutions - looking through that old Tasco beside the Nightforce is a night and day difference. Looking at the price tag between them is a night and day difference as well. I demo’d a Tangent Theta last month, and everything the Nightforce is above the Bushnell, the TT is over the NF.
You really do get what you pay for. Sure, one brand or model might be higher priced than another for the same quality, and more importantly, not every shooter NEEDS the image quality of $2000-5000 optics.
But it’s a disservice to lie to others to say there’s no appreciable difference between a $500 optic and a $1000 one.
