What you will learn: how the locate button works, what the teal marker means, and what to do if the browser refuses location.

Button name: locate / Go to my current location
Where: bottom bar on a phone; toolbar on desktop.

Locate does not track you in the background. It asks once (or until you revoke permission), then flies the map to that point.


Use locate

  1. Tap the locate control.
  2. If the browser asks Allow location, choose Allow.
  3. A teal marker appears on the map. The camera moves there (usually at least zoom 12).
  4. Inspect may open for that point so you can read depth immediately.

While it runs, related screens say Finding your location… / Locating….

If it fails

Message or behaviourWhat to do
Browser permission deniedIn the browser site settings, allow Location for app.algocatch.com, then try again. Safari and Chrome bury this under the lock icon next to the address.
“Map is not ready yet.”Wait until the chart finishes loading, then tap locate again.
“Your location is outside your allowed map area.”Some accounts are limited to a region. You are standing (or the GPS thinks you are) outside that box. Pan the map inside coverage, or contact support if that is unexpected.
“Couldn’t get location. Pick a harbour or explore yourself.”First-run sheet fallback. Use a harbour preset. See Your first session.
Marker is inland or hundreds of metres offPhone GPS is weak indoors. Step outside, wait for a lock, try again.

Desktop computers often have no GPS. Locate then uses a coarse network estimate or fails. Pick a harbour or pan manually.

Privacy

Other anglers cannot see your live position. Locate is for your map camera only.
