Pictures of first production transducer

[G. Burton]

Hi,
Some have been asking for pictures of a unit. I do not have a completed production sidescan together as of yet, only the prototype, although it works very well in all honesty looks like a POS. Things have gone slower than expected because of changes made in the commercial production sonar units that drive it, and nasty winter weather which prevents me from making full operational tests. Here at least is what I intend to be the first production transducer (Whoopieeee!).
Aprox 1.8 degree x ~ 30 degree beam battern. Connection to cable on backside.
As with all transducers I make, I want them to be tested under conditions where an image can be made that passes my inspection. Gotta get the ice auger out I guess.....
Regards

Nice work. How long has it taken you to develop this? Have you perfected it through simulations or on the water tests?

Hi,
Thanks. I test them by actual use in a nearby Reservoir. It is my intent to test every one that gets sold. Development is an ongoing thing, so its hard to tell the amount of time total.

How many elements do you use? Also, have you ever experimented with PVDF? I've read that you can form radiation patterns by selectivly etching the copper (similar to making a PCB).

Hi,
PVDF is not a good projector, although it's a fairly good reciever. Its usually used with a seperate projector.
