Lowrance HDS sonar question

[fishwater]

If you operate a HDS unit in the wide beam sonar does the unit still transmit the 200khz frequency like the Humminbird units do?

Nope, according to the Lowrance web site, 83khz is the wider cone angle, 200 khz is a 12 degree angle, the 83 khz is at about 120 degrees.

With the digital technology the standard 200KHZ transducer that we use can either be a 200 or 83 KHZ just by simply selecting which frequency you wish to run.

Thanks for the input guys. I got of the line with Navico and the Lowrance units only transmit a single frequency (from what I was told by a technical rep.) If this is really true and Lowrance can transmit only 83khz from a 200khz ducer, they are doing a sweet job with their new technologies. I have my fingers crossed this info holds true once I spend the money. I've been victimized by shifting technical specifications after purchase before...

I'm pretty sure the Humminbird dual beam plus works in the same way, generating 83khz from a 200khz crystal, but those units transmit 200khz regardless of selected frequency.
