Transducers for Dummies....like me
OK...I just got a Garmin 545s GPS Fishfinder without a transducer....so now I need to choose one (Transom Mount). I typically fish in waters less than 200 ft but on rare occaisions I may go deeper. What is the best choice based on your experience(s)? What is the difference between dual beam and dual frequency?
Here is what they offer...
200/50KHz 12/45 degree
200/50KHz 10/40 degree
200KHz 20 Degree
200KHz 45/15 Degree Dual Beam
Many thanks !
