Hello blue people!! 
We are pleased to introduce the bigger, badder sibling of the DVL A50 to our product line - say hello to the Water Linked DVL A125! 
The DVL A125 augments the capabilities of the A50 with an increased range up to 125 m and 600m depth rating, making it a good choice for larger vehicles and challenging operating conditions. It’s also better at measuring high velocities up to 9 m/s, making it a good fit for fast vehicles. Check out the product page for all of the details, and also don’t forget about the Smooth Operators Guide to to Underwater Sonars and Acoustic Devices if you need a refresher on doppler velocity loggers + all of the other kinds of navigational equipment!
