Could use some help from you salt guys. I 'm a freshwater fishing guide and I'm going to start exploring the salt waters soon. I have never used fishfinders so I dont know what to look for in one. I was looking at the Hummingbird 597 ci combo it has the down imaging and say it works to 250 ft.
Has anyone used the DI I think it would be great for my river fishing and also work good in the salt.
Looking for some first hand experience.
