Buying Guide- Which is Best Fish Finder Under 400 for you?
With so many fish finders on the market, finding the right one is not easy. Different anglers have different needs and fishing styles. So what may seem to be the best fish finder for you may not be a good option for another angler. So to help you make the best choice, here are some factors to consider:
The screen could either be colored, white black. Colored displays are however, the most preferred options because they are very clear. The size of the display screen also matters. You should go for a fish finder with a large display to allow you to view images with crystal clear clarity. Generally, fish finders with 5 inches and above display screen are the best.
Frequencies usually range from 50, 83, 192 to 200 kHz. Transducers with higher frequency are much better in terms of performance. Higher frequencies provide more details on the screen. For shallow waters, high frequency of up to 200kHz is more than enough. But for deep waters, low frequencies of about 50kHz is adequate.
A GPS is meant to provide easy navigation through the waters. Whilst some fish finders come with built in GPS, others don’t. This feature comes handy especially if you’ll be fishing throughout different locations. It makes it easy to find your way back home or the waypoints.
A transducer sends and receives Sonar wave’s signals. The signal is what is then translated into a picture. The most important thing to consider when checking a transducer is the cone angle. To get the most out of a transducer, it is recommended to go with the dual beam type.
All the fish finders we have reviewed above are top of the line devices. As such it is not easy to narrow this list of best fish finder under 400 down to just one. However, the Humminbird Helix 5 Chirp GPS G2 (410210-1) seems to offer a good bargain. When its Chirp Dual Beam and high frequencies are weighed against its low-cost, it’s clear why it’s our top choice. Whilst it has its own drawbacks, the unit boasts an intuitive Reflex interface and onboard GPS.
