Powered by the sun

Spotter is solar powered which means that you never have to worry about running out of power. Spotter V2 received updated hardware and firmware updates to make the system more efficient.

Rugged Design

The ocean is a rough place. Every part of Spotter is built to withstand the harshest ocean elements in any water condition, anywhere on our planet.

Compact and Portable

Roughly the size of a basketball, Spotter can be shipped anywhere around the world, carried by hand, and deployed without any special equipment.

Power Savings

With Spotter V2 we added advanced power saving options. These are designed to support extended deployments at extreme latitudes, including a 'hibernation mode' to overwinter extended no-light conditions.

Explore the Spotter Dashboard

The Spotter dashboard provides access to real-time and historical data and enables you to change your Spotters’ settings from anywhere in the world. You can set up alerts for weather conditions or get notified if your Spotter is outside of its geofence. You can also access data using the API or share your data with the Spotter mobile App.

Does Spotter have to be moored, or can it be free floating?

You can do both. Spotter can be moored in place for wave measurements, or be used as a wave-enabled Lagrangian drifter to measure both waves and track surface currents. The Spotter on-board analysis is designed with free drifting in mind, and will continue to measure waves accurately even in fast flowing currents.


How much global data service is included with Spotter?

Spotter comes with a free, one-year global data package. This free data period starts when you turn on your Spotter for the first time after registration, or within 3 months after registration, whichever comes first. The period of use is based on the standard transmission rate in Waves mode, but you will have full access to two-way communication and Track mode, and any new features we would make available during the period your real-time subscription is active.


Do I have to service my Spotter?

You don’t. Spotter is designed to operate continuously with no need for maintenance or servicing. Only thing it may need after prolonged deployment is a quick cleaning to remove marine fouling and growth, which in severe cases may affect motion response.
