<p class="MsoNormal">Hello Alan,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">To answer the questions you posed, the transducers are the same and the transducer itself would be able to survive the same depth as the diver units, 500 feet.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A more suitable option for them may be either using the hull mounted transducer, the TA-32M, if they want to stay with the STX-101 or by looking into the Bell-200 system. Links for the product pages to both are listed below. You can also
reach out to our sales team for more information on these options. <o:p></o:p></p>

<p class="MsoNormal">Hi,<br>
I am with a World wide group of submarine builders (<a href="http://psubs.org/">psubs.org</a>) who are using OTS <br>
wireless communication systems on our submersibles.<br>
One of our members is converting a STX-101 portable surface station unit for use <br>
inside the sub. This would require mounting the surface station transducer outside<br>
the pressure hull.<br>
My question is; are the surface station transducers as robust as the transducers on<br>
the diver units?<br>
Any estimates on their maximum depth?<br>
I see they can at least go down to 100ft ( length of transducer cable).<br>
Kind regards<br>
Alan James (New Zealand)<o:p></o:p></p>
