High powered fish finding

Many of the fish finders on the market have a narrow beam that limits your search. Some go as low as 20 degrees and others work their way up to 60 degrees. If you really want to get a broad expansive view of what is beneath you try the lowrance fish finder with the dual frequency search. This will give you 120 degrees of bottom viewing. It is easy to use with an auto zoom bottom tracking and alarms for deep, shallow or fish encounters. The unit we used was advertised for a depth penetration of up to 1000 feet.
