Nocpix Rico 2 S75R Thermal Rifle Scope

The Nocpix Rico 2 S75R LRF is the flagship of Nocpix's Rico 2 thermal weapon sight family — a true 1280-class thermal rifle scope built for hunters and precision shooters who want maximum resolution and the most refined optical and display package in the Rico 2 line. It pairs a 1280×1024 second-generation thermal sensor running at 60 Hz with a 75 mm F/1.0 germanium objective lens and an exceptionally generous 70 mm eye relief — paired with stepless digital zoom from 3× all the way to 30× and the full Rico 2 platform.

For the hunter who wants the most capable Rico 2, this is it. Detection past 4,000 yards, 1280-resolution image quality across that entire range, stepless zoom that lets you settle precisely where you want it without stepped jumps, and a viewing experience built around long sits and hardest-target identification. The S75R is what you buy when the question your scope needs to answer is "can I positively identify this target at this distance," and the answer needs to be yes.

The Rico 2 family — how the S75R fits

The Rico 2 series is a four-model tiered family on a shared platform. The naming code tells you the tier: L = 384 sensor, H = 640 sensor, S = 1280 sensor. The number that follows is the objective lens size in millimeters.

• L42R — 384×288 sensor, 42 mm lens. Entry into the Rico 2 platform.
• H50R — 640×512 sensor, 50 mm lens. The versatile middle of the line for medium-range hunting.
• H75R — 640×512 sensor, 75 mm lens. Long-reach 640 — same sensor as H50R, much bigger lens.
• S75R — 1280×1024 sensor, 75 mm lens, stepless 30× digital zoom. The 1280 flagship.

Step up from the H75R to the S75R when you want a 1280 sensor at the same 75 mm lens size — finer resolution and longer zoom range for hardest-target identification. The S75R is built for buyers who have used a 640 scope and want more pixel detail at long range, or who are stepping into thermal at the top of the line and want the platform that won't be the limiting factor in their hunting.

Why the 1280 sensor matters

A 1280×1024 sensor has roughly four times the total pixel count of a 640×512 sensor. More pixels collecting thermal data across the same scene means finer resolution at distance, cleaner edge definition on warm bodies, and easier positive identification when a target is small, partially obscured, or far away. On the S75R, those pixels work with a 75 mm F/1.0 lens that gathers maximum thermal signal — the combination is what makes 1280-class image quality possible at extreme range.

The 60 Hz refresh rate on the second-generation 1280 sensor keeps the image smooth on moving targets, which matters when you're scanning across pastureland or tracking a coyote responding to a call.

Why stepless 30× digital zoom matters

Most thermal scopes step through digital zoom in fixed increments — 2×, 4×, 8×. That means you can't settle the zoom exactly where the target identification gets easiest; you either zoom in too far or not far enough. The S75R's stepless zoom system lets you dial the magnification to any level between 3× and 30×, so you can find the precise zoom that puts the target at the optimal size on the display.

The 30× ceiling matters too. Most 640-class scopes max out at 8×. The S75R goes nearly four times further, and the 1280 sensor has the pixel density to make that zoom range useful instead of pixelated.

What you get with the S75R

• 1280×1024 second-generation thermal sensor, 12 μm pixel pitch, 60 Hz refresh. The top sensor tier in the Rico 2 family. Maximum thermal detail and smooth real-time imaging on moving targets.
• NETD ≤15 mK. Sharp thermal contrast and clean edge definition in difficult conditions — fog, light rain, low ambient temperatures, marginal heat differentials.
• 75 mm F/1.0 germanium objective. Maximum thermal signal gathering, paired with the 1280 sensor for the cleanest possible image at extreme range.
• 3× base optical magnification, stepless digital zoom to 30×. Wide field of view at base, then smooth zoom to any magnification in between.
• Detection range up to 4,250 yards. Identify heat signatures well beyond the engagement distance of nearly any thermal rifle scope on the market.
• 2560×2560 round AMOLED display. Crisp, immersive viewing across long sits — important on a flagship optic where you'll spend time studying detail.
• 70 mm eye relief. Exceptionally long — built for shooter comfort across extended sessions, and a safety margin on hard-recoiling rifles where eye relief matters.
• 23 mm exit pupil and distortion-free eyepiece. Clean, edge-to-edge imagery without the distortion that can show up at the edges on lesser optical packages.
• Built-in 1,200-yard laser rangefinder + ballistic calculator. Range a target, get drop data instantly using your input bullet velocity and ballistic coefficient.
• Picture-in-Picture mode with independent PIP magnification.
• Recoil-activated video and onboard recording for capturing the shot automatically.
• Magnetic charging port. Fast, intuitive recharges; spare battery included.
• Recoil-mitigating quick-detach mount included — the upgraded mount engineered for the 75 mm-class build and consistent return to zero.

Who the S75R is built for

• Precision long-range hunters who need 1280 image quality to make positive target identification at extreme distance
• Experienced thermal hunters stepping up from a 640 who want the next-level image
• Buyers entering thermal at the top of the line who want a platform that won't outgrow their hunting
• Predator and ranch operators working across large properties where reach and identification both matter
• Hunters who want the most refined optical and display package the Rico 2 platform offers — the 70 mm eye relief, the stepless zoom, the second-generation sensor

The trade-off versus the H75R is price and a small weight bump (2.87 lb vs. 2.76 lb), in exchange for the 1280 sensor, stepless 30× zoom, and the optical package built around the flagship's mission. If you've reached the limits of a 640 scope and want more image to work with, the S75R is the answer.

Frequently asked questions

Where does the S75R fit in the Rico 2 family?

The S75R is the flagship of the four-model Rico 2 series. The "S" signals the 1280 sensor tier; the "75" is the 75 mm objective lens. Below it sit the L42R (384), H50R (640 at 50 mm), and H75R (640 at 75 mm).

What's the difference between the S75R and the H75R?

Same 75 mm F/1.0 lens on both. The H75R uses a 640×512 sensor with 4× base magnification and 8× digital zoom. The S75R steps up to a 1280×1024 second-generation sensor with 3× base magnification and stepless digital zoom to 30× — roughly four times the pixel count, much finer resolution at distance, and a much longer zoom range. The S75R also has the longer 70 mm eye relief and distortion-free eyepiece. Detection range is similar on both (~4,250 yd) because the 75 mm lens defines the reach; the difference is image quality and zoom flexibility.

Is a 1280 sensor worth the upgrade from a 640?

For hunters who need positive target identification at extreme range, work in marginal heat conditions, or want to make confident calls on small or partially obscured animals — yes. The 1280 gives you roughly four times the pixel count of a 640, which translates into finer detail and easier identification at distance. If your hunting happens at distances where a 640 is making positive ID confidently, the upgrade may not pay off enough to justify the price step. If you're hitting the limits of a 640's resolution, the 1280 is what solves that.

What does "stepless" digital zoom mean and why does it matter?

Stepless digital zoom means the magnification can be set to any level between 3× and 30× — not just fixed increments like 4×, 8×, 16×. That lets you settle the zoom exactly where target identification is easiest for the distance you're shooting. Most thermal scopes step through zoom in jumps; the S75R lets you dial it precisely.

Why is the S75R's eye relief so long?

70 mm eye relief is exceptionally long for a thermal scope — built for shooter comfort across extended sessions and as a safety margin on hard-recoiling rifles. Long eye relief also makes the scope easier to use across different shooting positions without forcing your eye to a fixed spot behind the eyepiece.

Is the S75R a good thermal scope for precision long-range work?

Yes — that's exactly what it's built for. The combination of a 1280×1024 second-generation sensor, 75 mm F/1.0 lens, stepless 30× digital zoom, distortion-free eyepiece, 70 mm eye relief, and integrated LRF with ballistic calculator is the most capable Rico 2 configuration for identifying and engaging targets at extreme distance.

What battery does the S75R use and how long does it last?

Rechargeable battery with a magnetic charging port. Runtime is up to approximately 4 hours on a charge — slightly shorter than the L42R/H50R/H75R because the 1280 sensor draws more power. A spare battery is included with the scope.

Does the S75R record video?

Yes. Onboard recording with recoil-activated video — when the rifle fires, capture starts automatically.

Will the S75R hold zero through recoil?

Yes. The S75R ships with the recoil-mitigating quick-detach mount engineered for the 75 mm-class build and reliable return to zero on remount.

What's the warranty?

Nocpix backs the Rico 2 S75R with their standard manufacturer warranty.
