Tangent Theta vs ZCO vs Schmidt vs Kahles

[HuntnPack]

I've had both the TT 315 & the ZCO 420.
Both excellent optics. Decided I need more magnification on the top end. Only problem for me on a lighter build is optics with 30+ on the top end are typically Big & Heavy.
Got a couple NF in the safe I may run for now.
4-32's have not given me trouble Yet.

TT>ZCO>S&B........>Kahles.

I am a self-aware glass snob.
I now own 6 TT, 2 Premiers, 2 ZCO, 3 S&B, 1 Kahles, 1 March, 1 NF.

TT is king. No doubt about it. So let's call them 100% as the baseline.

TT 100%. Everything about them is the best.
Premier 98% (only because they are discontinued)
ZCO 97% (Don't sweat the 36mm tube, there are a bunch of great mounting solutions)
S&B PMII 93% (THE origina "gold standard", but the 5-25×56 are known to tunnel between 5x-7x)
NF ATACR F1 85% (Great glass, but has features I HATE)
March FX 85% (High Master glass puts it this high, the regular glass is on par with NF NX8/NXS)
Kahles 84% (great durability and tracking, glass is significantly less impressive)
NF NX8 75% (great cheaper option)

This is one of the best takes I've read online in at least a couple years.

Kahles is a fine optic, but it doesn't belong in the conversation with TT or ZCO.
Now, there are things personally that I would change to make any of them perfect, but you're really starting to nit-pick at that point.
I sold my TT a couple years ago but a 7-35 is high on my list of wants. Id like to see another revision to their reticle line ups first.
I'm not sure I'll ever sell my 5-42 HighMaster, but only because the deal I got on it was probably something I'll never find again. Again, the reticle options don't impress me and unless they had something significantly better...I don't see any reason to change.
i really wish Nightforce would abandon their mag ring being fixed to the ocular housing. I like to have caps on all my optics and I HATE that I can't adjust without screwing up the placement of my Tenebraex cap.
I've had a pair of Gen3 Razors so far, sold one and traded another for an Element 6-36 and don't regret that trade at all. Just hate that fake purpleish color they cling to. I'll grab another when I can find a Pre-Owned EuroOptic exclusive in Black.
I'd say a MK5HD probably belongs in that 75% to 80% bracket as well.

I don't have a Professional but some differences between the Marksman and LRH:
Marksman - exposed turrets, multiple reticles available, 27.8 ounces
LRH - covered turrets pull the cap up and it locks in, you then dial and push the cap back down. so turrets aren't exposed to possibly spin. LRH reticle is a bolder reticle with mil dots. same weight as the M.
Scopes are identical length etc...

@lancetkenyon can go much further in depth than me.

I believe there are significant differences in the amount of elevation adjustment that is available, with the LRH having the least and the P having the most.

Optics Comparison

Purpose As a competitive shooter, we often hear the question of which optic is best. While there are many components of an optic that contribute to the overall quality and its ability to perform, this review only focuses on optical clarity/resolution. The definition of clarity and resolution for...

Some food for thought. Not perfect by any means but a good baseline, take it with a grain of salt, especially due to sample variation.

Rifle Scopes - Optronika/Premier 5-25x56

I purchased another 2-25x56 Premier. This one says Optronika on one side and Premier on the other as well as made in Germany. Took it to the range not mounted on a rifle to compare with another Premier that is mounted to do some initial tests to see if it was a keeper. Passed all my initial...

Never had the chance to spend any time behind a TT but I did get the chance to look through a couple buddies ZCO 5-27 and March 4.5-28 side by side and to be completely honest the ZCO was very underwhelming... ZCO is the best looking scope but on that given day in those given conditions it didn't have an edge optically in any way shape or form over the March but what was very noticeable was the huge difference in FOV and the March destroyed the ZCO. After seeing those two side by side I lost all interest in a ZCO and before that day it was on the top of my list just going by all the reviews I had seen

Interesting. I've not used the ZCO 5-27 or the March 4.5x28. Like yourself, I have only read rave reviews on the ZCO scopes and intrigued by your assessment. While different models that are more compact in size,, I do own a ZCO420 and a March 2.5x25x52, both used quite extensively for LRH. My observations are that my March doesn't even come close to the FOV, optical quality, and low light performance of my ZCO420. Don't get me wrong, my March is a nice scope and has performed well for me but the improved performance of the ZCO is quite noticeable. As I'm an avid whitetail hunter, the ZCO420 gives an extra 10-15 minutes of visibility at dusk and dawn….Just my experience….

I should have mentioned the March I was comparing to the ZCO was the high master wide angle model and I looked through them mid day after a PRS match so lighting was good

The March FX 4.5-28x52WA High Master glass is night and day better than the old March F 3-24x52 in every aspect except weight. The 4.5x WA vs a 5x ZCO is the difference in FOV at low end.
The ZCO420 is almost unworldly, and hard to explain on how wide the image appears.
To my eyes, the ZCO glass is clearer and has better color and crisper. Maybe not so noticeable looking at a steel silhouette at 1K, but looking at fine details, it is noticeable.
I like the ZCO reticles better too.
If you get them both new, they are priced similarly. Neither one are easy to find used for a reason.

I've used all of the optics listed. I settled on ZCO. I run the 5-27 on my hunting rifles and the 8-40 on my competition rifle.

Where would the Zeiss S5 5-25x56 fall into your mix?
