Product Highlight
Concentrator Lenses: an inexpensive way to add more features to your DIDSON

 A concentrator lens is a plano-concave lens that fastens to the front lens of a DIDSON. The lens reduces the vertical beamwidth from the default 14 degrees to 8, 3 or 1 degrees depending on which concentrator is used.

Reducing the vertical beamwidth allows horizontal DIDSON beams to go farther in shallow rivers with reduced surface and bottom reverberation.

The front lens of the DIDSON must have four mounting screw holes tapped to use concentrator lenses. Newer lenses come with the screw holes standard, and older lenses can be sent to Sound Metrics for an upgrade.

See the DIDSON Product Options page for more details.



Software Highlight- Network Discovery

The latest DIDSON software V5.24.04 has a new command Edit->Sonar->Network Discovery. Sonars with firmware of 5-79 or higher may be able to broadcast their serial number, IP address, Ethernet Port and Broadcast status while waiting for an initial Ethernet connection, and if disconnected thereafter. Any sonar on the network may then be directly selected and its network information updated without having to go through the Edit->Sonar->DidsonV5.ini File command. This may be useful for troubleshooting connection issues, as well as for interfacing with multiple sonars on a network.

 
Co-founder and President
Dr. Ed Belcher Retires

 

ed at his desk

After seven years as President of Sound Metrics, Dr. Ed Belcher, 63, has retired. He represented DIDSON at the American Fisheries Society conference in Nashville, Tennessee August 30 through September 4 and will continue to represent Sound Metrics at exhibitions and workshops. Ed will still be in and out of the office in a consulting role, but for now he is enjoying his time at home finishing long put-off home improvement projects and planning possible trips to New Zealand and Panama. He and his wife Pam have put so much hard work and heart into the company over the years and we will miss seeing them both. We wish you all the best Ed!


DIDSON again featured on History Channel's MonsterQuest

DIDSON on a pole mount

Monster hunters used a DIDSON 300m SV on a pole mount in the "Jaws in Illinois" episode of MonsterQuest.

MonsterQuest, a History Channel feature that airs Wednesdays at 9 p.m., uses technology to gather evidence of elusive creatures all over the world from Bigfoot to the Lochness monster. DIDSON was first utilized on the show in 2008 to help monster hunters search for giant "killer" snakes in Venezuela. More recently in an episode that aired last October, DIDSON was used to search for bull sharks in Louisiana rivers to investigate a theory that sharks from the Gulf of Mexico had traveled as far north as Illinois. For the upcoming Season 4 of MonsterQuest, DIDSON serial number 120 is being called upon to locate schools of fish in the Lake of the Ozarks in Missouri before traveling to Surinam. Villages in the South American country have reported a high number of piranha attacks and DIDSON will be there to investigate. Stay tuned for more of DIDSON on MonsterQuest. Who knows what they will be searching for next!
