Re: what is the best fishfinder to buy for $150.00-$200.00?
I agree the fishmark 480 is the better unit but if you use the zoom I dout you can tell the difference fishing 60 feet or less.<br /><br />The transducer on both units is a 20 degree 200khz. In 30 feet of water you will see a 10 foot circle. In 60 feet you see a 20 foot circle. The UP TO 60 degrees is very misleading. The industry standard is to rate tranducer at the -3db half power point. Rated that way like all the other companies it is a 20 degree transducer. Instead they rate their transducer at the -10db or 1/10 power point. While you can pick up signals that weak you really can not see them displayed. To see that weak signal on the outer part of the cone you would have to turn the sensitivity up so far that the center part of the cone which is 5 times stronger would black out the whole screen. I guess the best way to say it is you get the same display that all the other honest company get with the same 20 degree transducer. If you do not belive this try and go to the acessories page and find a 60 degree transducer, you will only see 20 degree transducer.<br /><br />Also be aware that a 60 degree transducer that the 480 does not have will many times not show as many fish. Any time your fishing an uneven bottom or a sloped bottom where many fish hang out you will see less fish with a wider transducer. On flat bottoms the wider transducer will see more fish.<br /><br />16 levels of gray scale is just shades of gray form light to dark. The stronger returns will be thicker and darker.<br /><br />Both units like any good fish finder will show any iteam that will reflect sound. This includes fish, trees, bushes, rocks, leaves, plastic bags, air bubbles, soda can, water bottle, ect. The key to seeing small fish it to turn the sensitivy up. You need to be seeing false ruturns at the depth you are fishing to see all the small fish. The hardest part is to learn what you are seeing. For example a tree or a bush will often look like a school of fish as you move acrossed it.
