cv transducers are no longer produced by Garmin.

The cv units did not have a dedicated down vu element...so possibly less detail on down scan vs the GT version.
The GT units do have the separate dedicated down element..thus overall ...the GT may have the better results overall for structure under the boat.

You can use the GT23 8 pin with a 4 pin unit by adding the 8 to 4 pin adapter cable: 010-12719-00
