We are developing a new line of transmitters that will ultimately replace many of the workhorse transmitters you have been using.
We call these “Durasondes” because they are more durable due to their mostly metal construction.  In addition, they are more compact and easier to repair if necessary.

We are shipping the first Durasonde, the FD-10 (pictured).  This transmitter directly replaces the FM-10, and can attach to a push rod with a Dropcap fitting.  The FD-10 can be taped to a camera cable or jetter hose and can also ride in a standard Spring Carrier on the end of your power snake.

Stay tuned for further developments!
