new fish/depth finder

[Mac_Attack]

I have a Lowrance 339c got it last year but because of my surgery I did not install it til this year. It show the fish real well and the Gps is awsome using my trails. When we catch a fish just push WPT twice and it marks your position on the chart. Want to go over that spot again and again just follow your path on the chart. Drawback with internal antenna is that it does not comunicate with my Nmea 2000 buss system which means it will not display my position on my gauges. I don't need it to becasue it's already on the GPS/FF. Hope I did not confuse you too bad. Billy Mac ;D
