Spend a little extra and get a Lowerance. Also when you get one get one with 4000 Watts of power as it will give you better detail and less noise (they will tell you the 2400 Watt is plenty for around here but the 4000 W is the way to go). Eagles are the bargin brand of Lowerance and usually have lower power. You will be much happier with Lowerance.
