The CEO claimed that “Aquabotix has currently sold more than 400 vehicles in nearly 60 countries worldwide."

In March 2017 it was 350: http://www.iposociety.com.au/ipo-review-aquabotix-asx-uuv/

In September 2017 it was over 360 vehicles: https://hotcopper.com.au/threads/ann-investor-presentation.3672945/

Now its over 400 vehicles which points to a pretty big 4-months Sept-Dec with 50+ vehicles sold.
The last time they updated on average revenue per vehicle was July: "The Company has increased the average revenue per product unit from approximately $5,000 to approximately $15,000"

Likely somewhere in between those two now so $250,000 - $750,000 revenue for Sept-Dec. Hopefully they’ve managed to keep their average revenue per product high and it points to a pretty big quarter!
