Wireless Telemetry & Advanced Data Recording for Boats
Find out what's happening on the Water!
Whether your boats are nitro, electric, or gas, with
our Boat Data Acquisition products, you can stop guessing
about your boat’s performance and condition, and
find out what’s happening on your vehicle, after
the run or in real time! Simple to set up and operate,
our complete systems install easily to provide recorded
and wireless real time data at your fingertips!
Seagull Dashboard mounts on your Radio
The Seagull Boat Telemetry system (patent pending) has 3 main components:
Seagull Dashboard Telemetry Receiver - this unit displays telemetry data, and sounds alarms when problems occur.
Onboard Boat Data Recorder - this unit collects the data from built-in and external sensors.
Onboard Telemetry Transmitter - this unit sends the data from the Recorder to the Dashboard
These components let your monitor your model in 3 different ways:
The Dashboard displays the parameters you select, on multiple LCD pages, and also lets you program alarm levels for sounding alerts, i.e., low battery voltage.
The Dashboard also can connect (via built-in USB) to your laptop at the lake, to display and record data with our PC Virtual Dashboard software.
The onboard Data Recorder logs your sessions to permanent memory, so you can download the data to your PC via USB when you get home.
All hardware and software is included to monitor airspeed (with included pitot-static tube), RPM, temperature, 2 servo stick movements
and glitches, and receiver battery voltage.
Do you need even more data? Our Seagull Telemetry system is fully expandable, with a whole host of additional sensors, available below. Here are just a few examples of what you can do with additional sensors:
Monitor your electric power system with our Electric Expanders. These units measure power consumption with a small ring that is placed over one of your battery wires. No need to add an inline sensor!
Display your boat's path on Google Earth, either live at the lake or downloaded later, with the GPS Expander.
Monitor your Spektrum or JR Receiver's RF performance in real time, with our Spektrum FlightLog cable.
Monitor your boat's hull forces our Dual Axis G-Force Expander
Measure your Gas/Nitro motor's exhaust with our EGT Expander
Small, lightweight Boat Data Recorder
Do you only need Data Recording right now, and not Wireless Telemetry? You can order the Boat Data Recorder separately!
Machined aluminum/brass Prandtl Pitot Tube
We now also offer a waterspeed pitot tube option, which gives more accurate speed readings than the airspeed pitot tube,especially on windy or rough water days. For boats traveling at 50MPH or less, waterspeed can give more stable readings under rough conditions.
Waterspeed requires mounting the included brass tube under the boat. If you would like this $20.00 option, just select it when you order your products via clicking the Add buttons below.
