After my research it sounds like the FL 20 will be a great fit for me. Can anyone explain what ice-ducer size cone they like the best and why?
Depends on the depth you will be fishing. They have single beam with 12 or 19 degrees, dual beam with 9 and 19, triple beam with 8,12 and 19 degrees or the new Proview which is variable (i may be off by a degree or two but i think these are correct).
My FL18 has the 12 degree and it is great to about 90 feet or so.
I have my eyes open for a good deal on the dual, tri or pro view.
