Printing and exporting a slate
Export a deco schedule as a printable A6 PDF, a PNG image, or plain text for underwater reference.

What it is
The slate export turns your deco schedule into something you can carry underwater. You export the plan as a PDF sized for A6 paper, a PNG image, or plain text. Print the PDF, trim it, and laminate it for a wet-notes page or a writing slate. The layout is high-contrast and built for black-and-white printing, so it stays readable at arm’s length in poor light.
The slate is a quick-reference card, not the full planner. It shows the schedule and the numbers you need in the water, laid out to be legible when you cannot tap a screen.
Export a slate
Open the slate export
From your deco plan, open the menu and tap Export. The Export Slate sheet opens with a live preview, so you can see exactly what will print.
Pick the scenario
The scenario tabs at the top let you export the base plan or a contingency (for example +3 m or a lost-gas scenario). On a closed-circuit rebreather (CCR) plan you also get the view chips (loop ascent, full bailout, or bailout at a depth), so you can export the exact ascent you want on the card. Tap Add depth to create a bailout at a custom switch depth, then export that view. Custom-depth chips carry an X to remove them.
Choose optional columns
Below the preview, toggle the extra columns you want: PPO₂ (oxygen partial pressure), CNS (central nervous system oxygen-toxicity percentage), and Remaining Gas. The preview updates as you toggle, so you can see how wide the slate gets.
Export in your format
Tap Share as PDF, Share as Image, or Copy Text. The PDF and image go through the system share sheet, so you can save them, print them, or send them. Copy Text puts a plain-text version on your clipboard.
What the slate shows
The slate always carries the core schedule and the headline stats. The base table has four columns:
| Column | Meaning |
|---|---|
| Depth | The stop depth |
| Stop | Time held at that stop |
| Run | Cumulative runtime at that point |
| Mix | The gas (or mix) breathed there |
Above the table, the header always prints the plan name, GF (gradient factors, for example 50/80), TTS (time to surface), runtime (RT), ascent pressure, and turn time. Below the table, the footer always prints OTU (oxygen toxicity units) and CNS%, then labels the algorithm (Bühlmann ZH-L16C). None of these depend on a toggle. When you are exporting a contingency or a bailout view, the slate’s title says so, so a +3 m card never gets mistaken for the base plan.
You can add up to three optional columns:
- PPO₂: the oxygen partial pressure at each stop.
- CNS: the running central nervous system oxygen-toxicity percentage.
- Remaining Gas: how much gas is left as the dive progresses. On the slate this column is headed Bar or PSI (whichever pressure unit you use), not the words “Remaining Gas”.
Each extra column makes the slate wider, so the more you add, the smaller the print gets to keep the card on one A6 width. Toggle on only the columns you actually want in the water.
Choosing a format
| Format | Best for | Notes |
|---|---|---|
| Share as PDF | Printing and laminating | Vector output sized for A6 paper. Prints sharp at any size and paginates long plans across A6 pages, with the column header repeating and rows never splitting. This is the recommended path for a printed slate. |
| Share as Image | A quick photo to send or save | A PNG snapshot of the slate, captured at your phone’s screen density, so a higher-resolution phone prints sharper (about 1008 px wide on a 3x screen, 672 px on a 2x screen, roughly 244 or 162 dpi at 105 mm wide). It has no embedded paper size, so for a crisp laminated slate prefer the PDF. Fine for sending to a buddy or keeping on your phone. |
| Copy Text | A plain-text fallback | A text version of the schedule for pasting into notes or a message. |
Printing tips
The PDF is built for A6 paper (105 by 148 mm), a standard cut size that home printers, office paper, and slate guillotines all handle. To get a clean laminated slate:
- Print the PDF at A6 (or at 100% on A4 and trim to the A6 border). The PDF already includes a small printer-safe margin so nothing gets clipped at the edge.
- Trim along the page edge, leaving a little room around the content.
- Laminate it, or slip it into a wet-notes page.
If your plan is long, the PDF spreads the table across multiple A6 pages and repeats the column header on each, so a single stop never gets split between two cards.
