Do you have it interfaced with your computer or is it a separate unit? I'm looking at NMEA sounders which are relatively easy to interface with microprocessors but are expensive. Analog depth sounding transducers are much cheaper but I don't know how they present their information.</div><div dir="ltr"><br></div><div dir="ltr">Jon</div></div></div></div>_______________________________________________<br>Personal_Submersibles mailing list<br><a href="mailto:Personal_Submersibles@psubs.org" rel="nofollow" target="_blank">Personal_Submersibles@psubs.org</a><br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" rel="nofollow" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br></div>
