Humminbird 570 DI Portable

570 DI Portable

The Hummingbird Fish Finder 570 DI Portable, is quite a flexible, proficient and afforadble unit for what it can do. Although it doesn’t feature any GPS or chartplotting options, it’s a great device for finding fish, measuring depth, speed and water temperature.

Equipped with a 12 level grayscale display, 5″ diagonal, 640V x 320H pixel resolution, this unit will provide you with an excellent view of what’s underneath the boat. Even if it’s black and white, the images in Down Imaging are pretty clear and accurate. You will understand immediately where the fish are in relation to the boat, and make a good idea where to throw your lines. Plus, you can observe the bottom and the underwater environment in split screen, observing both the Switchfire and Down Imaging returns on your screen.

The sonar capability is 800/455 kHz for the Down Imaging option, and 455/200 kHz for the normal down beam sonar. In other words you can operate your Humminbird 570 DI Portable at two frequencies for Down Imaging: at 455 kHz to cover a wider area, with a 75° beam, or at 800 kHz, for a more accurate return caught by a 45° beam. The transducer of the 570 DI portable also uses two conical beams for 2D traditional imaging. With the 200 kHz you will obtain a view in a 25° beam and with the 455 kHz, a more focused image in a 16° beam.

This Humminbird unit has a 4000 Watts power PTP power output. It’s designed to be reliable for depths up to 500 feet in normal imaging. As when it comes to Down Imaging, you will benefit from reliable returns in waters up to 250 ft. deep.

The package contains a portable case and an AGM battery with its charger.

All in all, this is one of the best portable fish finders from Humminbird. It’s great to have especially if you’re not using your own boat on every fishing trip. You can take it along and install it quickly on your friend’s boat or on a rental boat, without drilling holes in it. The only downside about it is that sometimes the screen might be difficult to read in direct sunlight. In a case like this you should use something to create a bit of shade for the screen.
