Thermal Scope Reticles and Holdover: Shooting at Range

A thermal scope reticle is a digital aiming mark you select in software — usually a fine crosshair, a duplex, a single dot, or a ballistic reticle with holdover marks. Choose the style that suits your shooting, set a reticle colour that stands out against your thermal palette, and zero it to your rifle and load. For shots past your zero, use holdover marks or a dial to account for bullet drop — and pair them with a laser rangefinder when you can, so you know the exact distance instead of guessing.

Thermal changes the picture from a glass scope, but the fundamentals of aiming don’t change. You still need a clear aiming reference, a true zero, and an honest read on how far your bullet drops downrange. What’s different is that the reticle lives in software — so you can change its shape, its colour, and store more than one zero. That flexibility is a genuine advantage once you understand it. This guide walks through the reticle types, how to pick one, colour against palette, zero profiles, holdover, and the part that matters most: only taking shots you can actually make.

What is a thermal scope reticle?

On a thermal riflescope the reticle isn’t etched glass — it’s drawn by the processor and overlaid on the live thermal image. That’s why you can pick a different reticle from a menu, change its colour, and move it during zeroing without touching a turret. Pixfra units run this through their PIPS image processing, which handles the display and reticle overlay along with the thermal picture itself.

Because it’s digital, a reticle can be as simple or as detailed as you want. A clean dot keeps the target visible. A ballistic reticle gives you holdover references built in. The trade-off is always the same: more marks mean more precision at distance, but more clutter over a small or partly obscured target. New shooters often over-reach here and pick the busiest reticle available. Start simpler than you think you need.

What are the main thermal reticle types?

Most thermal scopes offer a handful of digital reticle styles. Exact options vary by model and firmware, so always check your unit’s manual for what’s on your menu — but these are the common families and what each does well.

The ballistic reticle is the one worth understanding properly, because it’s where holdover lives. It carries marks below the main aim point — dots, hashes, or a stadia line — that correspond to bullet drop at set distances once you’ve matched them to your load. More on that below.

How do I choose the right reticle?

Match the reticle to the job, not to whatever looks the most tactical. A few honest guidelines:

• Close, fast, moving work — dot or duplex. You want speed and a clear view of the animal, not a grid.
• Precise shots on small targets — fine crosshair or crosshair with centre dot. The thin lines cover less of the target.
• Known-distance shooting at range — a ballistic reticle, once you’ve confirmed the holdover marks against your actual load.
• Not sure yet — start with a simple crosshair or dot. You can change it in seconds from the menu, so there’s no cost to experimenting in the field.

What colour reticle should I use on thermal?

Here’s a thing glass shooters don’t have to think about: reticle colour that fights the image. On thermal, your reticle can usually be set to black, white, red, or other colours — and the right choice depends entirely on your palette and the scene.

The rule is contrast. Your reticle has to stand out against the part of the image you’ll be aiming at.

• White-hot palette — a warm animal shows bright/white. A white reticle vanishes over it. Use black or red so the mark sits clearly on the target.
• Black-hot palette — the animal shows dark. A black reticle disappears. Use white or red.
• Colour palettes (red-hot, and similar) — pick whatever cuts through cleanly; red can blend into hot zones, so black or white often reads better.

Don’t set it once and forget it. If you switch palettes between fields or conditions, glance at your reticle colour too. A reticle you can’t see over the vitals at the moment of the shot is worse than useless — it costs you the shot or, worse, gives you a bad one.

What are zero profiles and why do they matter?

Zeroing sets your point of aim to your point of impact — you aim at a heat-contrast target, shoot, and adjust the reticle until the shots land where the crosshair sits. It’s the non-negotiable first step, and thermal makes it easier in one respect: many scopes let you store multiple zero profiles.

That means one scope can hold a separate, correct zero for each rifle you mount it on, or for different loads through the same rifle. Swap the scope from the rimfire to the centrefire, select the matching profile, and you’re zeroed — no re-doing the whole process. If you run one thermal across a couple of rifles, this is a real, practical time-saver. Name your profiles clearly so you never fire the first shot on the wrong one.

For the full process — target choice, distance, and dialling it in — see our walkthrough on how to zero a thermal riflescope. Get the zero honest before you worry about anything downrange; every holdover in the world is built on top of a true zero.

How does holdover work on a thermal scope?

Holdover is how you account for bullet drop past your zero distance. Gravity pulls the bullet down the whole way to the target; the further out, the more it drops. If you’re zeroed at 100 and the animal is at 200, your bullet lands low unless you aim higher — you “hold over.”

You’ve got two honest ways to do it:

• Ballistic reticle marks — the hashes below your aim point correspond to drop at set distances for your load. Range the target, hold the matching mark on the vitals, and shoot. The catch: those marks are only right if you’ve confirmed them against your actual rifle and ammunition, not a generic chart. Verify on paper or steel at known distances.
• Dialling — some setups let you adjust for the known drop. Slower than a reticle hold, but precise when you have the time.

Either way, holdover depends on knowing two numbers: how far the target is, and how much your load drops at that distance. Guess either one and you’re guessing the shot. That drop figure comes from your specific load’s trajectory — build it from your own chronograph and range data where you can.

Do I need a laser rangefinder for holdover?

You don’t strictly need one, but it removes the biggest variable. Holdover is only as good as your distance estimate — and eyeballing range through thermal, in the dark, over unfamiliar ground, is genuinely hard. People are routinely 30 to 50 metres out, and that error alone can put a shot off the vitals.

A built-in laser rangefinder (LRF) gives you an exact distance in the moment. Range the animal, apply the matching holdover, take the shot — that’s how you make a clean cold-bore shot at distance. No mental arithmetic on how big a fox “looks,” no second-guessing. The Pixfra Pegasus 2 LRF builds the rangefinder straight into the scope, so ranging and aiming happen through the one unit. If you want ranging without committing to it on the scope, a handheld like the Pixfra Arc LRF monocular does the measuring while you spot.

Without an LRF, you estimate — using known landmarks, the reticle’s subtensions, or paced distances on familiar ground. It works, but it’s a skill with real error bars, and the honest move is to keep your shots inside the range where your estimate is reliable. If a built-in rangefinder is on your list, our rundown of the cheapest thermal scope with a rangefinder lays out the options and what you actually pay for the feature.

Which reticle is best for thermal hunting?

There’s no single best — there’s the best for your shooting. Fast close-range work on foxes and pigs rewards a dot or duplex you can settle instantly. Deliberate shots at range reward a ballistic reticle you’ve verified against your load and paired with a ranged distance. Most hunters end up with a simple reticle for the majority of their work and switch to a ballistic one only when they’re set up for longer, known-distance shots.

The reticle also has to suit the shot the rifle can take. Recoil, calibre, and the scope’s ability to hold zero all factor in — our notes on thermal scope recoil and calibre ratings are worth a read before you push a thermal onto a heavy-recoiling rifle. And knowing how far you can even detect, recognise, and identify a target sets a hard ceiling on shot distance regardless of reticle; our piece on detection, recognition and identification range covers exactly that.

The bit that matters most: only take the shot you can make

All of this — reticle, colour, zero, holdover, LRF — exists to serve one thing: a clean, ethical shot. Positive target identification first, every time. A safe backstop behind the animal. A distance inside your proven range with that rifle and load. If you can’t confirm all three, you don’t take the shot. A rangefinder and a ballistic reticle extend your capability; they don’t extend your permission to gamble. Know your zero, know your drop, and shoot within them.

Frequently asked questions

Can I change the reticle on a thermal scope?

Yes. Thermal reticles are digital, so you select the style and colour from the menu and can change them in seconds — including in the field. The exact options depend on your model and firmware, so check the manual.

What reticle colour is best on white-hot?

Not white — it disappears over a bright, warm target. Use black or red so the aim point stands out clearly against the animal. On black-hot, flip to white or red instead.

How do I use holdover without a rangefinder?

Estimate the distance using known landmarks, paced distances on familiar ground, or your reticle’s subtensions, then apply the holdover for that range. Accept that estimation carries error and keep your shots inside the range where your guess is reliable.

Do ballistic reticle marks work for any load?

No. The holdover marks only match a specific trajectory. Confirm them against your actual rifle and ammunition on paper or steel at known distances before trusting them in the field — don’t rely on a generic chart.

Can one thermal scope hold zeros for two rifles?

On most units, yes. Multiple zero profiles let you store a separate correct zero per rifle or load. Select the matching profile when you swap rifles rather than re-zeroing each time.

Where to from here

The reticle is the simplest-looking part of a thermal scope and one of the easiest to get half-right. Pick a style that suits your shooting, set a colour that reads against your palette, zero it honestly, and only reach for holdover once you know your drop and your distance. If precise ranged shots are your goal, a built-in LRF like the Pegasus 2 LRF takes the biggest guess out of the equation.
