I have an Axiom Plus RV with the
current Lighthouse 4.5.84
software on it.
Depth offset on this unit (hopefully similar on yours) as follows:
- from the Home
Screen, select one of the
depth views (e.g. Fishfinder)
- in a depth view, open the menu (select the 3 horizontal lines at top right)
- down arrow to get to the bottom of the menu, then select Settings (the triple
gear icon)
- select
Transducer
- now you can set your depth offset as below
keel, below waterline, or below transducer
