Bi-ducer 20 degree - common applications include G boats.
PLEASE NOTE THAT NAUTIQUE HAD A MID YEAR CHANGE IN 2023
All boats prior to 2023 used an 'airmar' unit and should have that name on the top of the unit.
Boats after a mid year change in 2023 used a Garmin brand.
Both units are compatible with the Linc software, however it is best to replace with like brands to avoid having to change out the entire thru-hull mount. These are from Nautique.
