To sum it up, in less than 60' the GT52 traditional chirp when compared to the GT51 in blue green saltwater conditions off the southern New England and Long Island coasts, including around Block Island, will:

Have better bottom detail,
Better fish detection,
Better target separation,
No noticeable difference from 60' to 150',
Functional to at least from 150' to over 200'.

For side and down vu:
Better less-than-60' imaging
No noticeable difference from 60' to 150'
Functional to 200'

Please, Semper or KMoose or other adjust my numbers if needed
