Thread: Somebody's been thinking...again...

I've wondered why HB decided to make and include the XNT 9 DI T with their "Dedicated DI" units...

As we know, the XNT 9 DI T has 2 Down Imaging "thin slice" beams of 455kHz 75°/800kHz 45° with an additional 2 conventional "cone shaped" beams of 200kHz 25°/ 455kHz 16°...

We also know that HB released a trolling motor mounted "Dedicated DI" xducer...the XTM 9 WIDE DI 20 T ...which has 2 Down Imaging "thin slice" beams of 455kHz 75°/800kHz 45° with an additional 2 conventional "cone shaped" beams of 200kHz 20°/83kHz 60°...

The HB website shows exactly 5 DI models compatible with the XTM 9 WIDE DI 20 T ....those being the 858c DI, 858c HD DI, 958c DI, 958cHD DI, 1158c DI....

It would seem to me that these 5 specific DI units will have a "Transducer Select" setting under the Sonar tab for "Down +200/83"...

What this confirms (I think) is that these 5 specific DI models are capable of transmitting the 200kHz/83kHz frequencies IF there is attached a HB Dual Beam xducer capable of vibrating the piezoes at 200kHz and 83kHz....

I examined the pin configurations of the XNT 9 DI T (that comes stock with the HB dedicated DI units)...and the AS SIDB Y cable and the XP 9 20 (standard Dual Beam 200/83kHz) and it seems that the pins are in the correct configuration of all 3 components for using a standard HB Dual Beam 200/83 xducer on the AS SIDB Y cable along with the stock XNT 9 DI T xducer and have the capability to employ the larger cone shaped beams of the XP 9 20's 200/83kHz Dual Beam...and still get the stock DI beams from the XNT 9 DI T ...

I could see this being a viable option for users that already own 1 of the 5 specific DI models above ...and happen to have an exta HB xducer laying around that is capable of 200/83kHz....

The only other purchase needed would be the AS SIDB Y cable to get the larger 200kHz 20°/83kHz 60° cone shaped beams along with their dedicated Down Imaging...





I do not own a HB dedicated DI unit to experiment with this idea so if anyone thinks they may be interested in trying this...you must understand ...

This setup is completely experimental and could very possibly cause unforeseen problems or catastrophic failure AND MOST LIKELY WILL VOID THE HB WARRANTY ...for hooking things to the HB unit not listed as compatible with that specific unit....

My OCD stays too busy some times...

I had been scratching my head on this because I have seen some of the DI unit guys talking about 200/83 but when I look it isn't there only 200. Guess I need to do a little experiment and see. Thanks for the info.

Talking with Greg seems to indicate that the "Transducer Select" option of "DI + 200/83" may have been added in a software version as the XTM 9 WIDE DI 20 T has only been available for a short time....which the 200/83 capability in the XTM 9 WIDE DI 20 T is the only reason why HB would have added that "Transducer Select" option of "DI + 200/83...

Redge ..what version are you currently on ...?

And do you have any newer versions you can load to show us which version the "DI + 200/83" option would have been added...??

And BTW...we can thank Greg for this idea...he already knew it was possible way before I researched it by chance notion from a question to me over at walleye central...
