You can run into a lot of trouble on fishing trips if you are not careful. This is especially true when you are fishing on a lake that is unfamiliar to you. Underwater obstacles can snare your fishing lines and in extreme situations can cause serious damage to your boat. These obstacles are difficult to spot with the naked eye. Finding your way back to a particular spot can also be a challenge in some instances. Lake shorelines may be too far away to use as a good judge of location. A marine GPS can alleviate these problems and help streamline and enhance your fishing experience. The average individual probably does not want to spend a thousand dollars just to find fish and avoid obstacles, and that is where the budget friendly models find their best use.
The Garmin Fishfinder 140 is one of these budget friendly options. It sells for about one hundred dollars and is equipped with a full feature sonar and 4.7 inch grayscale display. In order to help you see the display in bright sunlight, which is often a problem on a lake and when there is little cloud cover, the display has backlighting. It works effectively in shallow and deep water due to its dual beam transducer. It also refreshes the screen quickly, so as to give the user up-to-date information.
Another good budget option is the Humminbird PiranhaMax 170. It sells for around one hundred dollars as well. It has a 4 inch, grayscale display and uses a dual beam transducer to provide accurate information in both shallow and deep water. It also comes with the Humminbird FishID+ system. This system allows a user to set certain parameters and the device to alert the user when those parameters are met. It comes with a depth alarm that alerts the user to any underwater obstacles.
