WIDE" 2D CLASSIC PROBE PACK

TheHelix 7 G4 SI is available in a pack with the SH-B06T "Wide" through-beam probe which, unlike the other packs, does not feature Dual Spectrum technology but has a 60° wider beam.

Ideal for anglers not looking for exceptional image quality, but rather a large scan area and a greater depth of around 200m.

Wide frequencies : 83/200 kHz*

  • 83 kHz (75-95 khz) 60° angle
  • 200 kHz (175/225 Khz) 20° angle

*Only available as part of the Cross Probe package - Wide.



TRADITIONAL 2D DUAL SPECTRUM SOUNDER

The traditional sounder function uses Dual Spectrum coverage on a wider beam than usual, allowing optimum detection down to 100m without any problem.

With Dual Spectrum technology, you benefit from:

  • Denser information and sharper image in high resolution
  • Better target separation, sharper rendering of fish arches
  • Improved bottom tracking, detection even at high speed

Frequencies Chirp Dual Spectrum :140 -240 kHz

  • Wide beam at 140-200 kHz
  • Narrow beam 180-240 kHz

SIDE IMAGING TECHNOLOGY

See the underwater world as you've never seen it before, with crystal-clear vision from a distance of 120 meters on either side of the boat.

  • Frequencies Side Imaging : 455 kHz (440-500 kHz) with a side scan of 120m on each side of the boat.


DOWN IMAGING TECHNOLOGY

Get unprecedented clarity under-with coverage up to 120m below your boat. DI (Down Imaging) and MDI (Mega Down Imaging) technology shows what's going on under your boat, with near-photographic detail.

DI and MDI technologies use a thin beam directed downwards to take a succession of photographs of the seabed beneath the boat.

This enables fish to be detected very clearly. This is unquestionably the clearest, sharpest sonar image ever brought to market.

  • Frequency Down Imaging : 455 khz (405-535 khz) to a maximum depth of 120 m

AUTOCHART LIVE

The AutoChart Live function enables users to map and create bathymetry of any body of water for private use.

AutoChart Live software is pre-loaded with 8 hours of memory to give users the ability to create detailed bathymetric mapping of the seabed.

This feature now includes the ability to display vegetation variations and bottom hardness. Maps are created live on-screen as you prospect.

To increase the memory capacity of the AutoChart Live function, the AutoChart card is required.



GPS antenna

Humminbird Helix 7 features a state-of-the-art WAAS GPS antenna. This means you'll be able to pinpoint your position with the utmost precision, enabling you to do all your prospecting.

Thanks to its highly accurate built-in GPS antenna, you'll benefit from reliable navigation and detailed mapping.

A Micro SD card that can be used to display Humminbird CoastMaster, LakeMaster, Navionics, Navionics Platinium and SYLMAPS maps.

Please note that the Navigation card is not supplied as standard. (see model)

Questions / Answers (4)

Hello, I have a Humminbird HELIX 7 G4 CHIRP SI. Is-this model compatible with a MEGA Live probe? Thank you.

Yves Raymond , the 27/07/2025

No, the HELIX 7 G4 CHIRP SI is not compatible with the MEGA Live probe, as only G4N models (with the "N" for Ethernet network) are compatible. Your G4 model without the "N" does not have the necessary connections to use a Live probe.
