Nocpix MICRO2 H25 vs Ultra S25: Which Should You Buy?

The right choice starts with what you need to see and how you will carry the optic. A hunter scanning larger areas from a helmet may value the Ultra’s broader view. Someone who needs several operating roles but wants a lighter device and more standard runtime may prefer the H25.

Sensor resolution matters, but it does not settle the entire buying decision. Field of view, viewing comfort, battery use, mounting requirements, and the cost of the complete system all deserve attention.

Nocpix MICRO2 H25 vs Ultra Specifications

Battery life varies with conditions and enabled functions. The maximum power-saving figures include restrictions explained below. Clip-on support also depends on the day optic and mounting arrangement. The manual describes different display scaling by operating mode, so neither product should be described as having the same viewed magnification in every configuration.

The Ultra’s Biggest Difference Is Its Wider View

The Ultra’s published horizontal field of view is 34.2°, compared with 17.5° on the H25. That is approximately 95% more horizontal angular coverage. Its 25.9° vertical view is also nearly twice the H25’s 13.1°.

For helmet scanning, broader coverage can help you observe more of a field edge or surrounding area in one view. If you mostly watch a smaller area, that extra coverage may be less valuable. The practical benefit depends on how and where you use the device.

Does the Ultra Have Four Times the H25’s Detail?

The specifications do not establish that. The Ultra has 1,228,800 total sensor pixels; the H25 has 327,680. That is 3.75 times the total pixel count. The Ultra also uses those pixels to cover a wider scene.

Total sensor pixels should not be presented as an equivalent increase in identification distance or detail on the same animal. A useful comparison shows the same subject at the same distance, with operating mode and viewing settings identified.

The often-quoted four-times pixel comparison applies to the Ultra versus the older RH25 V2’s 640x480 sensor. Existing owners can use our MICRO2 vs RH25 V2 upgrade guide for that comparison.

Who Should Buy the MICRO2 H25?

The Nocpix MICRO2 H25 is a practical starting point when you want the platform’s four operating roles but do not need the Ultra’s broader view.

Its published optic weight is 1.7 ounces lower, and its standard runtime is approximately two hours longer per battery. Those differences can matter during longer sessions.

• Your usual scanning area is adequately served by the 17.5° horizontal view.
• You need several operating configurations and want to budget for the complete mounting system.
• You value longer standard runtime and lower device weight.
• You would rather spend on the supporting equipment you need than automatically choose the larger sensor.

The H25 shares the Ultra’s display resolution, but the thermal sensors remain different. A display presents the image; it does not change the resolution of the sensor capturing it.

Who Should Buy the MICRO2 Ultra?

The Nocpix MICRO2 Ultra S25 is worth considering when the wider view directly serves your scanning. Experienced helmet users and buyers planning a paired-device system have specific reasons to compare it.

• You regularly want more surrounding terrain visible in one view.
• You have allowed for the additional device weight and complete mounting system.
• You understand its shorter standard runtime and have a suitable power plan.
• You will use several operating roles rather than buying unused capability.

If only one role matters, compare dedicated options before choosing either multifunction model. Browse our helmet-mounted thermal collection and thermal clip-on collection to compare different approaches.

What Both MICRO2 Models Share

Both models use a 25mm f/1.0 lens, 60 Hz refresh, ≤15 mK NETD, and a 2560x2560 AMOLED display. Both support three clip-on zeroing profiles, Dual-Link for paired MICRO2 devices, Flip Standby in helmet mode, and NV Highlight and Outline display modes.

They also provide 64 GB storage, photo and video recording, microphone support, recoil-activated video, and USB-C external power.

Feature availability depends on operating mode. Digital zoom is disabled in helmet and clip-on modes. The 10x clip-on figure refers to the supported setting of a compatible day scope. It is separate from the device’s digital zoom.

For mounting and configuration planning, read the MICRO2 helmet setup guide.

Compare Standard Battery Life Before Maximum Runtime

The manual lists approximately 6.5 hours of standard runtime for H25 and 4.5 hours for Ultra. Auto Power Saving extends the published figures to up to nine and six hours respectively. Each device uses one replaceable 18650 battery at a time; the manufacturer package list includes two batteries.

When Auto Power Saving is active, the manual says Wi-Fi, Bluetooth, the microphone, and recoil-activated video are turned off. Recording is unavailable until the device wakes, and enabling those functions disables the saving mode.

If you want recording, remote access, or linked operation, plan around the functions you intend to use rather than assuming the maximum battery figure includes every feature.

Compare the Complete Setup Cost

A useful price comparison includes the optic, helmet components, role-specific adapters, and power accessories. The manufacturer’s package list includes a 1.93-inch OEM rifle mount; PICTAIL is optional and not included. The optic alone is not automatically a complete helmet kit.

Check current pricing, bundle contents, and fulfillment information on the product pages. Browse the Nocpix collection if a different product class would better fit your use.

MICRO2 H25 vs Ultra Frequently Asked Questions

Which MICRO2 is better for helmet use?

The Ultra offers a wider published view. The H25 has lower published weight and longer runtime. The better choice depends on your scanning needs and the fit and balance of the complete system.

Does either model have a built-in laser rangefinder?

No. The manufacturer manual lists no built-in rangefinder for either model.

Does NV Outline mean the device includes night vision?

No. Highlight and Outline are thermal display modes intended to support pairing with a separate night-vision device. They do not add a built-in digital night-vision sensor.

Is the Ultra automatically better at identifying animals farther away?

The sensor and field-of-view figures alone do not establish that. Compare relevant imagery at your intended distances and conditions. A detection rating is not an identification guarantee.

Are MICRO2 H25 and MINI2 H25 the same?

No. They are separate product families. Match the exact model and SKU when comparing specifications or ordering accessories.
