Thanks everyone. What is this graph worth?
788 ci sonar & GPS. Good condition and comes with transducer.
You need to be aware of ALL of the 788 models.
There are four of them.
788c Combo---------Sonar external GPS antenna
788ci Combo--------Sonar internal GPS antenna
788ci HD Combo-----Sonar internal GPS antenna
788ci HD DI Combo--Sonar/Down Imaging internal GPS antenna
ONLY the two with HD
in their model names are Ethernet capable.
All four of them are INTERLINK connectable with the 1198c SI Combo.
The AS INTERLINK has been discontinued and you may find some old stock or a used one.
