Fishing is a little like real estate – it’s all about location, location, location! Instead of aimlessly wandering from spot to spot hoping to find a school of fish, a portable fish finder can help you narrow down the areas where the schools may be feeding. However, finding a good fish locator can be as hard as finding the fish! There are different models, with different wattage, screens, and prices. How do you narrow down your options? In this article, we’ll explain how these machines work so that you can break down the elements and snag yourself a great bargain.

Portable fish finders are a wonderful gadget that can actually help you locate fish if used properly. Prior to the invention of this equipment, fishers utilized a depth finder that only indicated the deepness beneath the boat. There was no accurate screen indicating the existence of schools of fish. Therefore, depth finders were of little use to commercial fishermen. Next there were the sounders with printed graphs rolls that were extremely precise if utilized properly. However, the real innovation was the arrival of the LCD (liquid crystal display) sounder that showed both fish and bottom contours. Currently there is a wide variety of these LCD fish finders.

Selecting the right portable fish finder is sometimes complicated as the market pricing is very competitive and products are being updated at all times. Top of the line models can cost more than the typical dinghy, but basic devices can be completely affordable and cost as little as $300 from a discount fish finder retailer.

The technology has come some distance from the time when electronic fish finders first appeared on the market. Today’s finders are more slender, lighter and more menu-driven than their predecessors. The units have both color or black and white displays and the screens come in many sizes. The bigger displays are better suited to bigger fishing vessels where they can be kept out of the sun and elements. These are just the thing for commercial fishing vessels.

The key to the effectiveness of a fish finding sonar is its transducer housing. This is essentially the working part that scans the area beneath boat and transmits the information back to the screen where you can see it. By bouncing a sonar signal, you’ll be able to see fish, weeds and underwater structures. How quickly this echo signal process takes depends on the portable fish finder wattage, the transducer and the depth of the water. The higher the wattage, the more powerful and quicker the signal is processed from the transducer.

Proper installation and maintenance are key to keeping your portable fish finder in working order. It should be in a convenient place that is out of direct sunlight and rain. A fish locator will be waterproof but prolonged exposure to sun and water will shrink and decay the neoprene casing. You should also make sure that the monitor is well placed. The pixels that make up the image can appear blurry if the angle isn’t correct. If you don’t have good vision, then you might want to spend a little more on a screen with a higher resolution. By doing your homework and making good choices when shopping, you’ll definitely notice a marked volume in your catches.
