i am just finally understanding how to widen the beam and see fish .

. i did come to the conclusion that the scope goes to about 147' in custom mode . of course salty pirate has probably concluded this for himself? if we could grab just another 50 - 80 feet . can you give me a few pointers on doing the update salty ? i did the download . unzipped files , put card in , and started the computer . the system says version 1.86 - 1.9 . it should say 2.01 ? what am i doing wrong? thanks for help .
