When it comes to marine electronics for fishing, you have a wide array of choices. You can even get an iPhone app called FishHead that tracks weather, tides, and lunar information! But for most people, fishing electronics usually means fish finders or GPS systems. They can be bought separately, or in combo units saving mounting space and money.
There are several things to consider when choosing boat electronics for fishing.
When it comes to transducers on fishing electronics, there are single frequency transducers and dual frequency transducers. Single frequency transducers are used for lakes, while dual frequency shouldbe used when you are fishing in deep water. In deep water, the higher frequency transducer on a dual transducer fish finder is the one that will show all the fish.
You can also get display screens on marine electronics with many different resolutions. Indeed, higher resolution, brings better image. You can see color screens better in direct sunlight. The overall size of the display may be anywhere from four to seven
inches, measured on the diagonal. Generally speaking, the more power your fishing electronics come with, the better the results, even in still or shallow water. Depth penetration is related to the power and quality of the transducer. Better transducers penetrate the water best. Muddy and or salty water may limit how deep your finder will work.
Norcross makes a portable fish finder with many new marine electronics features including several sensitivity settings and a mountable and side scanable sonar sensor. To use it, you need to power it on, toss the floating sonar sensor overboard and get instant fish, depth, weed, and contour readings on the handheld monitor device. It updates depth readings four times per second for high accuracy, and you can have the information displayed in meters or feet. The LCD display blocks glare with Polarized VirtuView technology and SoftGlow backlighting. It has an audible fish alarm and enables accurate measures of weed height.
Eagle makes a line of inexpensive to mid-range fishing electronics that are boat mounted. Some of them have grayscale screens, and some are color. The color screens are easier to read in bright sunlight. Those fish finders start at below 100 dollars.
Humminbird is also a popular line for marine electronics. athough they, too make cheap fish finders, they also have severa more gadgety models – such as a combination wristwatch / fish finder, and specialized fish finders for ice fishing.
Lowrance is considered one of the higher end providers of marine electronics, including fish finders. They feature larger screens and higher resolution than the more basic brands, though they, too, make a couple of more affordable models, and one model specially designed for ice fishing.
Marine electronics for fishing include combination systems and other devices that combine multiple features. You can buy a fish finder for $100 and you can pay several hundred, too. Your specific needs and budget should determine which type of equipment for fishing will best suit your needs.
