Factors to Consider When Shopping For Fish Finders

When looking for a fish finder for your boat, you need to consider how much resolution you’ll need. The better the display is, the easier it will be to read information and make adjustments. Most fish finders today have color screens. Color displays have a higher pixel count, making the information much easier to read, especially when the water is cloudy or the sun is out. best fish finders

A fish finder’s accuracy is greatly reduced if the transducer is positioned in an area with protrusions or a deadrise angle. This angle, which is the flat point of the boat, can offset the transducer by as much as 8 degrees. To avoid this problem, you can use a leveling block to keep the transducer flat. The leveling block must be even and accurate to ensure the best results.

New fish finders usually come with full installation instructions. The first step is to drill mounting bracket holes and locate the control/display unit. Most of these units run on a 12-volt D.C. source, so be sure to choose a model that has a power connector with fuse protection. You should also route the power and transducer cables through the boat.

Another important factor to consider when shopping for a fish finder is battery life. The best fish finders use rechargeable batteries. However, many SLA batteries last only a few hundred recharge cycles. Some don’t even make it to 500 cycles. A battery life of at least 2,500 to 7,000 cycles is ideal for a fish finder.

In addition to range, hull mounted fish finders can be easier to use. These devices have a wider range and more accurate results than transducers that are mounted on the transom. They are also more durable than transom mount transducers. However, hull mounted fish finders aren’t the best choice for every boat.

The next factor to consider when shopping for a fish finder is the power. The power of the transducer will determine how well it can find fish in deeper waters. High-wattage fish finders will work better in deep water, while low-wattage ones are better for shallow water.

Another important factor to consider when shopping for a fish finder is the cone angle. A wider cone will cover a wider area under your boat, but this may decrease its sensitivity when used in shallow waters. The angle is also important because it directly affects the depth at which the fish finder can be used.

A fish finder with high frequency output will show much more detail in the display. A fish finder with low-frequency transducers won’t show target separation.
