Hi All, So i've just bought a HDS Live for my boat, and now i have that in the front and an older Gen3 unit at the back. I have an old Lowrance 50/200 transducer but i want to upgrade that considering my equipment, what would you recommend for someone who fishes the ocean for salmon/halibut and does prawning etc? I was looking at that 3in1 transducer but i wonder if that's excessive and has features that are of limited use in the ocean. Would love feedback from those who have one. Thanks!
