The COROS Dual-Device Fishing System

To get the most out of your time on the water, you need to balance two things: staying focused on your cast and bait presentation but also on collecting and analyzing changes that impact fish behavior. COROS solves this challenge through its dual-device fishing system.

By utilizing a real-time Bluetooth connection, the watch handles GPS tracking and hands-free inputs on your wrist, while your smartphone acts as a high-visibility computer. This educational guide explains how this integration works and how to use it while you're fishing.

Turn Your Phone into a Fishing Dashboard

The Extender screen in the COROS app is another possibility to visualize and record information during your fishing sessions. Instead of keeping your phone tucked away in a pocket, you can mount it securely to your kayak, float tube, or boat console to display all of the live data capture.

After starting an activity from your watch, as long as there is an established bluetooth connection, Extender and the data being collected will be visible in the COROS app.

Viewing Live Data

When you look at the Extender dashboard on your phone during a session, the screen is divided into clear, data-driven segments. Here is what you can monitor in real time:

• Activity Time: This tracks the total time spent in the fishing activity mode.
• Distance: Displays the total cumulative distance you have traveled.
• Catches: A live counter showing how many fish you have logged during the active session.
• Waypoints: Every waypoint is instantly marked on your screen.
• Moving Direction: A live compass and heading indicator that shows your precise drift or travel direction.
• Mapping: Displays your map and your position on it, to see your travel, and set directions.
• Weather Information: Displays live temperature, weather, wind direction and speed, and moon phase.

Record Information

Your phone can complement the use of the watch by editing waypoints and taking photos during your activity.

Take Pictures

Visual evidence is key to remembering water clarity, weed growth, or other useful information that you can use the next time you visit that body of water.

How to use it: Tap the camera icon directly on the Extender interface on your phone.

The result: The app snaps the photo and automatically attaches it to the exact GPS coordinate you were at when the photo was taken, embedding it into your session timeline.

Mark a Waypoint

Marking Voice Pins or manual pins, Catch, Cover or Structure is essential for mapping your favorite body of water and highlighting points of interest.

1. Using Voice Pin

This is the optimal hands-free method when you are holding a fish or managing your tackle with wet hands.

How to use it: Press the microphone button and start speaking your observation naturally ("10 pound Bass caught with a heavy action rod and 1oz watermelon punching jig", "Large weed bed, three feet deep").

The result: The watch converts your voice memo and immediately syncs it to your phone. A custom icon appears on your phone’s live map at your exact GPS coordinates with the audio file and transcript attached.

2. Using Manual Pin

If you prefer a quick tactile input or want to log a spot quietly, you can use the manual pin system.

Tap the "Mark Waypoint" icon directly on the phone's touch screen dashboard. This allows you to select custom icons Pin, Catch, Cover or Structure on the spot.

You can also add voice records or pictures to your manual waypoint.
