Fish Finders – Are Fish Finders Designed to Stay on Bost?
While some fish finders are designed to stay on a boat, others are designed to attach to a trolling motor. This method is useful for fishermen who are alternating between trolling and fishing. Placing the transducer beneath the boat will give the fish finder a more accurate reading of the fish’s movement. Thankfully, most fish finders come with suction cup attachments for the transducer. These are easy to install and portable. In addition, they don’t pose a structural risk to your boat. fish finders for kayaks
Some fish finders also come with a chartplotter, which is useful for avoiding underwater hazards and recording your fishing spot. Whether or not you want to use this feature depends on your needs and budget. Some of the more advanced fish finders even have transducers that can look ahead and around.
Another option for fish finders is a touchscreen. With the touchscreen version, the fish finder has a more intuitive user interface similar to a smartphone. However, fish finders with buttons are often more convenient for people who are driving the boat or who are in water with a lot of swells.
Another option is down imaging, which uses a transducer to emit thin slices of high-frequency sound waves. This creates a lifelike 3D image of what’s beneath the boat. The transducer’s imaging system can paint this information onto the fish finder, so you can see the structure below in a whole new way.
A fish finder’s frequency determines the depth and details of the image. A regular 2D fish finder uses a cone-shaped sound wave to ping the water column directly beneath the boat. A higher frequency means a narrower cone beam and better definition. Lower frequencies, on the other hand, give more coverage area and lower frequency signals are more useful in mid and shallow-water.
The portability of a fish finder is another important consideration. A fish finder must be easy to mount on the boat. Most of these devices are mounted around the base, and usually come with mounting hardware. They are more portable if they are battery-powered. A battery-powered portable fish finder is an excellent choice for small boats.
Fish finders are constantly evolving and becoming increasingly sophisticated. While the most basic models can show depth and other basic bottom information, more advanced models show an incredibly detailed bottom image with color displays and topography. Some also show changes in temperature. These can help an angler locate fish that are hiding in deeper water.
While some fish finders are made for small boats, others offer premium features and use smartphone apps. The Garmin Striker Cast, for instance, offers all the features of a $1,000 fish finder. It is compact, has a suction cup transducer, and has a GPS. While it costs more than other models, it’s worth trying it out if you have a small boat.
