Airmar CAST™ App Icon


CAST™ provides users with the ability to easily view, analyze and share sensor data to evaluate and improve performance. Simply install the CAST™ app on your iOS device to view available NMEA data over a BLE or network connection. Create custom gauges and page views to see only the data that is important to you. CAST™ allows the user to perform speed, temperature, and attitude calibrations without the need for additional converters or cables. And, in addition to firmware updates, the app also logs all of the NMEA sensor data over a customized time period for analysis. Smart devices with Bluetooth® connectivity can be used to view the data, creating a mobile powerhouse for your application.

SensorCheck™ App

The TDT1000 Transducer Diagnostic Tester compares the transducer onboard your vessel to its original specifications when it left the Airmar factory. Simply install the SensorCheck™ app on your Bluetooth® LE-enabled smart device, connect to the TDT1000 and get started! Accurately test both traditional and Chirp-ready transducers that operate at frequencies ranging from 10 kHz to 500 kHz. With Chirp-ready units and any traditional units over 1kW and above, the TDT1000 will automatically read Xducer ID® features such as transducer model, frequency, part number and serial number. When the test is complete, custom reports are automatically generated and can be emailed directly to the boat owner or even an Airmar technician.

The TDT1000 kit includes test unit, test cables, TDT test block, power supply, carrying case and Quick Start Guide.

We’ve got you covered.

Airmar Signal K

Signal K Download for SmartBoat Modules

The SmartBoat® system for onboard sensor connectivity and control is now Signal K compatible. Signal K’s community of users and developers now has access to connected analog sensor and engine data with this free software download to their SmartBoat module. Multiple sensors, regardless of protocol, interface directly with the modules, which converts the sensor data to Signal K, enabling boaters to control the data and set alarms. With built-in Wi-Fi, ethernet and NMEA (0183 and 2000) connections, a SmartBoat module provides a one-device Signal K solution, eliminating the need for multiple, expensive translation modules, engine conversion boxes and cabling. This makes it the most compact and cost-effective method of implementing Signal K.
