Reticle Studio

Design a custom rifle-scope reticle right in your browser — crosshairs, BDC ladders, christmas-tree holds, chevrons and more, all to exact MIL/MOA subtensions. When you're done, export it as a file or grab a short code to load it straight into the Zima Ballistics app.

Reticle Studio is a brand-new feature under active development — things may change and you might hit the odd rough edge. Spotted a bug or have an idea? Let us know.

How to use Reticle Studio

About the presets

The built-in presets are independent approximations of third-party reticles — Trijicon (ACOG), Leupold, Horus (TREMOR 3) and ELCAN. Zima is not affiliated with these brands and they have not provided reticle data; presets are for illustration and as starting points only.

The basics

Add an element — open + Add and choose a shape (crosshair, dot, hash ladder, chevron, christmas-tree, BDC ladder, label, and more). It drops at the center.
Select & edit it — click the element on the canvas (or in the left Elements list). Its settings appear in the right panel — sizes are in MIL/MOA to exact subtensions.
Position it — drag the element on the canvas. It snaps to a fine grid, and locks to the center axes (you'll see a blue guide line) when it's close.
Try a preset — open Presets to load a complete real-world reticle as a starting point.

Zoom, move & select

Zoom: scroll your mouse wheel / trackpad over the canvas (zooms toward the cursor), or use the + / − buttons (the fainter pair below them is fine ±1% zoom). The ⊕ button (or F) re-centers and fits the view.
Move / pan: hold Alt/Option and drag, or drag with the middle mouse button. Arrow keys nudge the view too.
Select: click an element. Cmd/Ctrl+click adds more to the selection; click empty space to deselect.
Reorder / group: drag rows in the Elements list to change draw order; select several and group them.

Keyboard shortcuts

`Cmd/Ctrl` + `Z`	Undo
`Cmd/Ctrl` + `Shift` + `Z`	Redo
`Backspace` / `Delete`	Delete selected element
`Arrow keys`	Pan the view
`F` / `Home`	Fit & recenter
`+` / `−`	Zoom in / out (`]` / `[` = fine)

Reference image & finishing

⊞ Ref loads a photo or PDF of a real reticle to trace over — adjust its opacity/scale and lock it in place. It never appears in your exports.
FOV sets the scope field-of-view the reticle is designed for (this is metadata — separate from how far you're zoomed in).
Export when done: download a .reticle.json file, an SVG/PNG, or tap Get Share Code for a 6-character code to load it in the Zima Ballistics app.

Tip: hover any button or field in the builder for a one-line explanation.
