Update on fish finders. Thanks to the great advice and Brian at BBG marine. I purchased a helix 10 g2n gps for the bow and a Helix 9 mega chirp g2n for the console. I also made my choice on the boat, I ordered a lund 1875 sport with the crappie option yesterday. Now to wait for the boat to get here. 8 weeks will be a long time. I went with the plain 10 at the bow to reduce cost and the 9 mega at the console to reduce cost also. I did get the heading antenna for the bow unit. Thanks again
