Choosing High-End Fish Finders
There are several factors to consider before purchasing a high-end fish finder. The power draw can be anywhere from twelve to 200 watts, but some fish finders can take much more power. This is especially true of those with backlights. If you’re planning to use your fish finder for long periods of time, you’ll want to look for a fish finder with dual frequency capabilities. hummingbird fish finders helix 7
The power draw of a fish finder is one of the most important factors when choosing a device. The higher the power draw, the deeper the readings will be. However, if you’re fishing in shallow water, a low-wattage model will work just fine. A high-wattage fish finder will produce faster waves and provide more accurate readings. While a high-wattage model is more powerful and is ideal for deep water, a low-wattage model is best for shallow water.
Another factor to consider is the frequency. Some high-end fish finders use low-frequency transducers, which transmit sounds in a conical shape. While these are best for shallow waters, higher frequencies are more accurate in detecting larger fish. You should also consider the depth capability of the unit, as many high-end fish finders have multiple frequencies. Ultimately, it is your preference which frequency you choose, but remember that you’ll be paying for your fish finder’s capabilities.
The power draw of a high-end fish finder is an important factor, as many electronic parts are powered by batteries. Batteries can last for many years with proper care. It’s also important to consider the weight of the device, as a fish finder’s battery can weigh up to 6 pounds. If you’re using it while kayaking, you’ll want to consider a lighter option.
A lithium-ion battery is the best option for a fish finder. Lithium-ion batteries are lightweight and small compared to their counterparts. Additionally, lithium-ion batteries deliver a steady current to the electronics. The downside of a lithium-ion battery is its cost. However, you’ll get a long battery life for a 12-volt fish finder by choosing one with lithium-ion batteries.
When choosing a transducer, it’s important to understand the frequency range that is supported by the fish finder. For example, a Humminbird MEGA unit requires a transducer that can generate 1200 kHz frequencies for ultra-clear images. Garmin also offers megahertz capability in some of their GPSMAP and ECHOMAP units. SideVu, however, requires a GT56UHD-TM transducer while DownVu supports only 455 and 800 kHz.
Garmin is a popular name in GPS tech. Their Striker Plus 4 fish finder is a great option for someone starting out in the hobby. It features a dual-beam transducer and mapping technology. The 7-inch display is highly detailed and comes with a touchpad. Its powerful transducer and navigational integration make it a great choice for many fishermen. But beware that the Striker Plus 4’s 200-watt power draw is not ideal for serious fishermen.
