I just got the Lowrance LXC 104-C on my new boat and it simply awesome... you will not be sorry.
I got the dual frequency unit... the 50 KHZ will really help in the salt where you can actually track your downrigger line and ball down to the fish, :shocked: thats where you want to use it, but I think my unit has the wider angle with the 200 KHZ.
I can easily spot sturgeon on the bottom with my unit. Yesterday when I was out I marked only small fish in one of my usual haunts moved up stream graphing the bottom along the way... 200 yrds up marked several nice fish, anchored above them and within 15 minutes had 3 keepers! Very unfair, very nice
