Humminbird Helix 7 CHIRP Si GPS G2 features a built-in GPS receiver with EGNOS, WAAS, and MSAS and offers quick fixes with an accuracy of 2.5m. In case you are after a superior mapping experience, the unit is compatible with the Navionics Gold/Hot Maps, LakeMaster, and SmartStrike cards. They do not provide a lot of details, but they do cover inland lakes and the contiguous US coastline at 30m per pixel. Humminbird Helix 7 CHIRP Si GPS G2 comes with preloaded UniMap charts, which are the most basic iteration of map charts commonly found in Humminbird devices.

However, you have to install the ZeroLines, Navionics or LakeMaster card in order to use this feature. This means you can map/remap any body of water and make sure you always use the latest depth contours. One of the fanciest features Humminbird Helix 7 CHIRP Si GPS G2 has to offer is AutoChart Live, which allows you to scan the depth contours of any body of water based on the data provided by your 2D sonar. Humminbird Helix 7 CHIRP Si GPS G2 also features numerous standard sonar functionalities, including Sonar Recording, Selective Fish ID+ with Fish Alarms, Real-Time Sonar, SwitchFire, Bottom Lock, Split Zoom, and Screen Snapshot. The transducer you get with the unit is the XNT 9 Si 180 T, which comes with a plastic gimbal mount and an optional in-dash. The maximum depth capability with a 50/200 kHz transducer is capped at 2,500ft.

Humminbird Helix 7 CHIRP Si GPS G2 has its maximum depth capped at 1,500ft for DualBeam Plus and at 150ft for Si and Di. Note that the Side and Down Imaging provide you with almost photo-like scans and work best for observing and understanding underwater shapes and structures, but the 2D sonar is still better for discerning fish targets. Humminbird does not provide information about the specific angles for Down Imaging, but there are 3 different scanning modes: wide, medium, and narrow. The Side Imaging beams cover 86В° and can reach up to 240ft on each side of your vessel. The unit uses 455 kHz frequency (modulated between 420-520 kHz) for Down Imaging and thin sonar beams instead of conical. Note that the provided transducer uses conical sonar beams that operate at 60В° for 83 kHz and 20В° for 200 kHz.

If you want to cover the low CHIRP as well (50 kHz modulated over 28-75 kHz), you have to upgrade the unit with a 50/200 capable transducer.

Since it utilizes the CHIRP technology, the ping is modulated over 75-95 kHz and 175-225 kHz, respectively.ДЄs we already mentioned in this Humminbird Helix 7 CHIRP Si GPS G2 review, the DualBeam Plus 2D sonar allows you to observe the scans made by both beams simultaneously in the split-screen mode. The unit itself can cover 50, 83, and 200 kHz when it comes to the 2D sonar, but the provided transducer is only capable of 83/200 kHz. Humminbird Helix 7 CHIRP Si GPS G2 provides you with DualBeam Plus as well as Side and Down Imaging, boosted by the CHIRP technology for better target separation, superior underwater observation, and less excess clutter.
