## What is AirmarCAST™?

Airmar® CAST™ connects to the Bluetooth®-enabled DST810, DX900+, WX300 multisensors and SmartBoat® modules on your boat, making sensor configuration and calibration easy with intuitive app navigation and real-time data from your multisensor. View data on detailed gauges and digital data screens, and perform speed, temperature, and attitude calibrations without the need for additional converters or cables.  With CAST, you can configure your multisensor directly, regardless of the other displays and gauges on board. All data configurations and calibrations are stored in the multisensor and delivered on the NMEA2000® network. 

When used with DST810, you can calibrate basic or heel-compensated speed through water using your on-board GPS speed for comparison. Intuitive wizards guide you through multiple runs to correct for current. Or take it a step further to advanced speed calibration, with up to five heel angles and ten reference speeds. Until now, advanced speed calibration was only possible through expensive PC based software. 

With Airmar’s SmartBoat® modules, the CAST app delivers the fastest connection to the SmartView software for system configuration.

### 4/5 — Used with new DST820

*2026-07-09*

I installed the DST820 on my boat and used the app to configure the output.  Havent used it to calibrate my speed but it looks pretty straightforward

### 2/5 — Needs work

*2025-09-16*

1. Settings menu is confusing bc it only gives units options while all all other settings require swiping left which I had to locate the manual to figure out. 2. Pressing plus sign sets up another device page so now I have two useless ones from trying different things, and now the app is “hanging” and resets every time I swipe past the useless device pages. Make the pages editable to remove modules and delete the page. 3. Work with BnG to have Airmar DST 810 option on Zeus chartplotter setup. I had to select “generic”.

### 2/5 — Units are incorrect

*2022-01-02*

No matter the setting the app report temp & depth units in C and meters.

### 1/5 — Broken unit conversions

*2021-07-02*

Knotmeter readout displayed in degrees by default. Depth label changes to feet, but clearly still meters. Same for temperature.
