water to output depths. 
 

Bluetooth

 

When red light is blinking the system is powered on, a Bluetooth connection is now 
available. You must connect with your collection device of choice (refer to your data 
collector manual). When Bluetooth is connection is on, a solid blue LED light will appear. 
 

Serial 

A serial cable is included to output data from the Sonarmite. Transducer must be 
connected and red LED light blinking to output data. 
 

Data Collection 

The Sonarmite has eight output formats, depending on the software used for data 
collection. Changing these formats and also sound velocity will be covered in a 
separate section below. Please visit our website support section for the specific setup 
guides for your system:

Bar checking

 

Bar checking is calibrating the system for the sound velocity of the water you will survey 

 in. There are only two methods of doing this:  
 
1. A digital bar check (example Odom Digibar Pro).  
2. Building a bar check consisting of a flat, large base at a fixed distance from the 
transducer. For shallow water use you can use sound velocity tables to set your 
Sonarmite close to the desired setting. To do this you would get a water temperature 
from mid water column and refer to proper sound velocity table for fresh or salt water. 
Please call if you have further questions. 
 
Using the seabed for calibration is not acceptable; this should only be used for rough 
check. 
 

Internal Battery Charging 

Charge the battery the night before using, every six months you can do a discharge 
and full recharge.
