Re: I Want to buy the right Fish Finder
A fishfinder uses sound waves to provide you with a display that shows the bottom and any objects that bounce the audio signal back. The system shows a graphical display of where you are, and where you have been. So you can tell for example if the depth is geting shallower, or deeper. The unit also acts as nice digital depth meter.<br /><br />The fishfinder aspect comes into play as the air chamber in fish reflects the signal back. With experience, you will be able to tell when you fish pass below your boat.<br /><br />If you are not into fishing, the device is still quite useful in giving you a good view of what is below you.<br /><br />As for models, I really like the new Raymarine digital units. They call them HDFI or some such thing. The unit I have is quite expensive but now they have low cost units for a few hunderd dollars. Most people rave about Furuno but I find their dispalys really poor and their analog systems much more difficult to use (the digial Raymarine systems have auto gain which makes thema breeze to use).<br /><br />Amir
