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.

Afloat Plan Home for anyone who boats, kayaks, canoes, jet skis, or paddles Purpose: To submit a plan while recreating on the water. Let others know you arrived home safely. Have someone search for you if you don’t come back. Submit via text message all the details of your planned water sports activity. Choose 5 contacts to receive a description of your boat, kayak, jet ski, paddleboard, or canoe. Setting up the app is easy, and you only do it once. • Enter your name, address, phone number, and contact information. • Complete the description of your watercraft—hull numbers, registration, size, and colors. • List your emergency contacts so they are contacted if you are late and do not end your trip. File a float plan in just a few easy steps. Type in your starting location, what your destination is, and what the arrival or return time are. When you push submit, it sends a description of your watercraft, with your starting location and a Google map link, to your contacts. During the course of your activity, your location will be captured every 10 minutes and stored in the cloud. The app continues to acquire your GPS location via satellite and track your trip even when you are out of LTE range. When you are out of range, trip location data is archived locally on your smartphone or tablet. As soon as you reenter LTE range, your offline trip locations are synchronized with the cloud. In the event you don’t end your trip at the scheduled time, the app will send a notification for you to end your trip. After 15 minutes, it will remind you again to end your trip. If after 30 minutes you have not ended the trip, the app will send your trip map to your contacts with route information and your last known location. If you have a Sirius Signal model C-1002 SOS eVDSD, you can test and turn on your signal remotely. The app also shows the light’s battery status. The app also includes an offline interactive looped audio first aid treatment guide for common on-water emergencies.
