FAQs
Should I adjust the diopter first? How do I do it?
Yes, always start with the diopter. Focus on UI text or a distant light source until the letters or icons become snap-sharp. This ensures the display matches your eyesight before you use the monocular.
How do I focus on the objective lens?
Adjust the objective focus at about 100–200 yards, then refocus whenever the distance changes. This helps maintain sharp target outlines at different ranges.
Which color palette should I start with?
Start with White-Hot for general scanning. If the background is warm or cluttered, try Black-Hot or Ironbow. This improves target contrast and makes spotting easier.
How should I set brightness and contrast?
Set brightness slightly lower, then increase contrast one or two steps. This makes micro-details in the image pop without washing out heat signatures.
Should I lower the horizon in view?
Yes, try to keep the sky out of the frame. Including trees or ground stabilizes auto-gain and reduces sudden brightness changes.
How do I use PiP if supported?
Use Picture-in-Picture to zoom on head or shoulder, while still keeping the full scene visible. This helps with small or distant targets without losing context.
Should I enable hotspot tracking?
Yes, if available, enable hotspot tracking. It will automatically snap to warm targets in thick cover, saving you time when scanning dense areas.
What’s the best scan cadence?
Sweep slowly and deliberately, pause on suspicious shapes to let the image settle. This ensures accurate readings and reduces false targets.

How do I set the units correctly?
Just power on your device and switch to yards (U.S. default). Keep it there so you don’t accidentally mix yards and meters.
How do I adjust the diopter?
Look at the sky or a white wall and twist the eyepiece until the reticle looks sharp. Always do this before measuring.
Should I pre-map ranges before a hunt?
Yes! Check 100/200/300 yd landmarks before the hunt and remember them. It makes measuring distances in the field much faster.
How do I track moving targets?
Press and hold the measure button to start scanning. This smooths out hand shake and heat shimmer, so even moving targets give steady readings.
Where should I aim on a target?
Aim for hard edges like shoulder lines, antler bases, tree trunks, or rocks. Avoid open fur or grass tops — they’re tricky.
How to bracket small targets?
First, measure a nearby solid object (stump/rock), then the actual target. Do a second scan to confirm.
How do I handle steep shots?
Use angle-compensated distance for uphill or downhill shots. Double-check with your ballistic app or card.
Any tips for low-light?
Turn up reticle brightness if available. Aim at edges or silhouettes, not just dark body areas.

Laser Rangefinders
My rangefinder isn’t reading the target. What should I do?
First, try ranging a nearby trunk or rock. If the device reads those correctly, it means your laser was hitting grass, leaves, or empty air instead of the solid target. Adjust your aim to hard edges, and you should get a proper reading. Doing this helps you quickly figure out whether the device is working or if it’s just the target that’s tricky.
The numbers seem all over the place. How can I fix it?
Switch to Scan mode and focus on a distinct edge of the target. Keep your stance stable, elbows tucked, and gently exhale before pressing the button. This reduces hand shake and mirage effects, giving you smoother, more reliable readings instead of random fluctuations.
Why does my device keep reading the background instead of my target?
If the device locks onto the background, try reducing the reticle area (if possible) and aim at the base of the target rather than a top or side that blends in. Re-scan to confirm. This ensures the laser focuses on the solid object you want to measure, preventing confusion from trees, rocks, or distant clutter.

Thermal Monoculars
Everything looks like glowing blobs. What can I do?
Try lowering the brightness, slightly raising contrast, refocus the eyepiece, and switch to Black-Hot. This helps separate heat sources from background noise, giving clearer shapes and improving recognition.
The image is always soft. How can I fix it?
Reset the diopter, perform a Full FFC, clean the lens gently, and refocus at your target distance. This ensures sharpness and removes sensor drift or smudges that blur the image.
I see banding or vertical columns. What should I do?
Perform a manual FFC. If the issue persists, note the current temperature and contact service. This resets sensor calibration and helps technicians assess any underlying hardware concerns.

How should I clean my lens to avoid scratches?
You can start by gently using a blower to remove dust, then a soft brush, and finally a microfiber cloth or lens wipe. Avoid rubbing dust dry because that could scratch the lens.
Do fingerprints or sunscreen affect performance?
Yes, they do. Try to keep both the emitter and receiver lenses clean. Even small smudges can make the image less sharp or change heat readings.
Can I use alcohol or chemical cleaners?
It’s better to use only optics-safe cleaning fluids. Alcohol or other solvents may haze the coatings and make the image look foggy.

Is Germanium really delicate? How should I handle it?
Yes, treat the objective lens like jewelry. Scratches are permanent, so always handle with care and avoid touching it unnecessarily.
What’s the best cleaning sequence?
Start with a blower, then a soft brush, and finally a lens tissue. Never use a T-shirt or rough fabric — they can scratch coatings.
Should I keep the lens capped in sunlight?
Absolutely. Always keep the lens cap on when moving or storing. Don’t park the device facing the sun — excess heat can damage the sensor.
