ITC-5 not recognizing transducers

[Steve - Raymarine - Moderator]

The possibility of two iTC-5 being bad is very unlikely. Despite your transducer tests. The only way to confirm would be to send the iTC-5 to the below address to be evaluated by a service technician.

Raymarine Service Center
9 Townsend West
Nashua, NH 03063

Include in the box:
Name
Daytime Phone
Return address
Brief description of the issue

This way we can confirm if the issue with the iTC-5 or the speed transducer.
