HDI

HDI skimmer transducer models: 000-10977-001 and 0010976-001

Which units are these transducers compatible with? I've seen a few websites say the Elite 7 and Gen 2 touch. What about the regular Gen 2 or even 3 and Carbon are they compatible with those units and then also is Elite 7 the only Elite series unit that is compatible with this transducer?

Also do you need the little black box if you are using with a Gen 2 and Gen 2 touch?

HDI works with all HDS touch units and previous Elite units. You can used it on the Elite Ti units, but you need make sure you get the right HDI unit (9 pin HDI transducer).

The "976" is the 83/200/455/800 and the "977" is a 50/200/455/800. The difference is in the low frequency sonar beam.
