Humminbird HELIX CHIRP GPS Review

Humminbird continues to be the best fish finder for the UK market, strictly because of its GPS function that really contours to our map (not just designed for US use, for once).

You can add a micro SD card for expanded storage, or use the on-board memory to store images of maps and previous routes for later use.

 

CHIRP dual beam and PLUS sonar work together to give consistently accurate information, with a small 615mA power draw for better battery life.

Raymarine packed a punch with this sonar and GPS combo, displayed on a 17.7 cm display with vibrant color and perfect clarity so you know exactly what you’re doing at all times.

Designed for power above everything else, Raymarine definitely charges a premium, but includes the built-in down vision, and CPT-DVS without needing an SD card to run it.

Lucky Wireless Fish Finder Review

Often hailed as the best fish finder for a small boat, this lightweight unit doesn’t require a lot of power to turn on and run well.

With nearly 9 cm of visible screen space, you get vibrant color to see everything on, although a low resolution.

With audible alerts, you’ll always know when fish are close and when it’s the right time to cast that reel. From 1 to 100 meters, you’ll know where everything is.

Built to be the best fish finder for kayak use as well as ice fishing use.

Portable Fish Finders FAQ

What Should I Look for When Buying a Fish Finder?

Fish don’t remain static. They’re constantly on the move, meaning you have to get up-to-date information as often as possible. For this, you want multiple scans in any given minute, as well as GPS navigation.

Display is also important, because information is useless if you can’t effectively read it. LCD screen size and brightness settings matter, specifically because of screen glare during bright daylight hours when we’re all commonly fishing on our boats.

Usability, battery life, and a comfortable UI is also important. At the end of the day, you want extensive, up-to-date information on a visible screen.

How Does a Fish Finder Work?

Fish finders use sonar, which is actually an abbreviation for sound navigation ranging. This is like a miniature version of what you can expect to see in submarine sonars, with little to no impact on marine life.

A sound pulse is sent out, and it returns back to the fish finder with information. Upon returning, another pulse is sent out to bring more up-to-date information in front of you.

Are Portable Fish Finders Any Good?

Yes, they can be useful, but they don’t have the best battery life. Almost all portable fish finders are powered using lithium-ion batteries, and while these can be hooked up to and charged by personal 5W solar panels (which you can mount on your boat), it might not be enough to sustain an all-day fishing affair.

Do You Really Need a Fish Finder?

You don’t need one, but they’re helpful. The fun of fishing isn’t sitting by and waiting for your reel to catch something; it’s about casting, catching, and pulling it back to shore (or the side of your boat).

Fish finders help drastically cut down the time you have to spend actually finding a good fishing spot. Not to sound bleak, but with the way marine life is shrinking due to overfishing and pollution, it’s not going to get any easier to find fish in the near future.

Do Cheap Fish Finders Work?

They work, but not well. You can expect a cheap fish finder to perform basic scanning up to about five or ten meters in the water, but depending on where you’re fishing, it won’t be enough. You don’t need a fish finder for lake fishing, but if you were going to use one, a cheap one would do the trick.
