FishFinder cone angle?
I currently have an inexpensive fish/bottom finder with a 20deg cone angle
and am having very much trouble locating "obstructions" on the bottom where I fish (in the gulf out of Pensacola). Many of these were points were converted from Loran to GPS and only go to 2 decimal places, or within 52.8ft. My GPS might be within 10-20ft and the 20deg cone, at 50ft, if my trig is right, is just over 18ft. Most of my fishing would be in the 40 to 100' depths. In short, it takes a lot of passes to locate a car body or even a larger object such as a sunken tug or barge. I think the Hummingbird Matrix 37 with a 90/20 dual cone or the Eagle Trifinder with up to a 150deg cone would help locate these wrecks. Is my logic good? Am I missing something? |
