How Sonotronics is making a difference in the world we share …
“Marlin, Thank you for your extraordinary effort in helping us overcome deployment and technological challenges we face in Grand Canyon. Our sonic telemetry project to determine the impact of the March 2008 High Flow Event on rainbow trout movement in Lees Ferry was a success because of your and your staff’s determination. We were able to deploy 90 transmitters in rainbow trout, the smallest of which was 157mm. We detected these tags before and after the flow with manual tracking and by using the submersible ultrasonic receivers. Interestingly, tagged trout did not displace downstream during the high flow. Thank you for your good humor and determination through this challenging project!” — Kara D Hilwig

A Look Back… Sonotronics product development history
How customers are using Sonotronics’ products
“… Furthermore I would like to inform you of an AWESOME recent finding. One of the 260cm female lemon sharks that was equipped with a Sonotronics 4 year transmitter was detected on our SUR array in Bimini for multiple days at the end of May this year. This shark was tagged in Bimini on May 19th 2007 and has not been detected since then. This shark was therefore at liberty for 2 years and the transmitter was still working on her return to Bimini – MASSIVE THANK YOU to you and all your team.” — Tristan Guttridge, PhD Student, University of Leeds, UK
