Take your maps far beyond signal.
The BathyMaps Companion app puts detailed bathymetry on your phone — contours, depth shading and the full colour palette, with your position, speed and heading live on the chart. Download the regions you fish and the whole map works completely offline: every contour, every colour, full detail, 40 km from the nearest bar of signal.
OFFLINE, PROPERLY
• Pick a region on the map, see its exact size before you commit, and watch it land in seconds — the new download engine pulls whole regions at over 100 MB a minute.
• Add high-resolution satellite imagery for your spots: position a box over the water you fish and save reef edges, sand patches and channels for offline.
• Prove it before you leave the ramp — the offline simulation button makes the app behave exactly as it will with no signal, so you can check your coverage in ten seconds.
• Saved access keeps working for weeks between connections, and the app shows you exactly how many days remain.
TILT INTO 3D
Tap 3D and the seabed rises into living terrain — contour lines and depth labels draped over every ledge, gutter and pinnacle. Pan, pinch and twist to come at a feature from any angle, and wind the exaggeration up to make subtle structure jump out.
YOUR MARKS AND TRACKS
• Every waypoint from your BathyMaps account, sorted by distance and bearing from where you are right now.
• Drop a mark on the crosshair with one tap; file it into groups with notes, bait, tide — whatever matters.
• Made marks out wide with no signal? They queue quietly and sync next time you're connected.
• Record your tracks with a running timer and distance, pause and resume mid-drift, and keep a logbook of every session — recording contributes depth data, so today's drift becomes tomorrow's contour.
STRAIGHT TO THE SPOT
Got numbers from a mate, a magazine or your old sounder? Spin the coordinate wheels — degrees, minutes, seconds, no fiddly typing — and the map flies straight there. Save it as a waypoint or just have a look.
BATHYMART, SYNCED
Ultra-high-resolution surveys purchased on your BathyMaps account appear on the chart automatically, razor-sharp over the surrounding bathymetry — and they come along inside your offline regions too.
MADE FOR THE WATER
• Depth palettes: PaleoMaps, Deep, Original and Satellite.
• Dynamic palette rescaling, contour intervals from 0.5 m, adjustable terrain lighting.
• Coordinates in DD, DDM or DMS; speed in knots or km/h.
• One login for web and app — your BathyMaps plan covers both.
A BathyMaps subscription is required to sign in. Coverage focused on Australian waters.
Sharper satellite imagery
The Satellite basemap now uses new high-resolution imagery, giving you a clearer look at reefs, shoals, channels and shorelines.
Faster, smarter imagery downloads
• Satellite imagery downloads are faster.
• The download box now follows your zoom: zoom in to grab smaller areas one at a time, or zoom out to take a bigger area in one go.
• The download progress is easier to read, with a large percentage and the time elapsed.
Your map layers stay on top
Marine park zoning, boat ramps, place names and other map layers now show over the satellite imagery.
Quicker Offline Regions
The Offline Regions screen opens straight away, and storage totals update as soon as you download or delete an area. BathyMart products now show their correct size.
Thanks for fishing with BathyMaps. Tight lines!
