Recently got a adapter cable to pair a radarsonics 1 kw single element transducer to a 1871f that is a dual frequency 50/200 and cone angles of 45/11 degrees. I know I could put in a generic 1 kw and not get accufish, but if I put in the 50/200 it 1 kw for accufish with an 8.5/28 degree cone, will my fish length be skewed?
