Tools
Free planning tools built around the questions jumpers actually ask before a load — distance to DZ, wind footprint, conditions. More tools land here as we build them.
Wind-adjusted canopy reach
Spotting Tool
Spot the exit point in real numbers. From your opening altitude, in today's winds at altitude, where does your canopy actually reach over the ground? Labeled in miles + km so you can compare against your altimeter's distance-from-DZ readout.
Open the tool →Wingloading + APF chart lookup
Wingloading Calculator
Wingloading + the APF Canopy Downsizing Chart in one place. Punch in exit weight, canopy size, and jumps — see your wingloading, the chart's recommended minimum, and a red/yellow/green reality-check on where you sit vs the conservative guideline. Guideline only, never clearance.

DZ Board
Full-screen wall display for a dropzone — live jumpability verdict, surface + winds-aloft, spotting map with safe/max glide rings, sunset and time-left. Auto-refreshes every 10 minutes. Bookmark it on a classroom or hangar TV and it just runs.

DZ Board · TV setup in 5 steps
Set up the board on your DZ's TV
Five steps. No app, no install, no account.
- 1. Pick a TV. Any TV at the DZ — gear-up area, bar, briefing room, second monitor next to your manifest screen. A wasted TV is a perfect TV.
- 2. Get something to drive it. A Chromecast, Fire Stick, Apple TV, Raspberry Pi, or any old laptop/mini-PC that runs a browser. Cheapest path: a $30 Fire Stick.
- 3. Open a browser and point it at your DZ's board URL. It looks like
jumpslut.com/board/your-dz-slug. Don't know your slug? Find your DZ in the directory and use the same slug. - 4. Set the browser to fullscreen (F11 on most, or the kiosk-mode setting on smart-TV browsers).
- 5. Leave it running. The board auto-refreshes every 10 minutes — observed winds, gusts, the spotting map, sunset, your next event.
That's it. No subscription, no setup fee. Want a printable setup sheet for your manifest team? Download the PDF guide or read the full walkthrough. The board help page covers setting it up and what to do when something looks wrong.
Running Burble on your manifest screen? The board sits perfectly on a second TV (bar, briefing room, gear-up). Don't share the manifest screen — give the board its own.
