Key Features Explained
On high-definition waters, the aerial image overlay can show features such as creek-channel entrances and exits, reef or weed-line extent, shallow-water rock piles, and drop-offs. The highlighted depth range can help distinguish shallow areas within the selected range, while synchronized contours and shorelines reflect the actual water levels described for the waterway.
Compatibility, Size and Fit
Compatibility depends on the specific GPS-equipped unit. The card is listed for all HELIX, SOLIX, ONIX, and ION Series models and select 600-1100 Series models. The description does not identify which 600-1100 models are supported, so check the exact model before selecting the card. The included SD adapter is part of the package, but does not establish compatibility with an otherwise unsupported unit.
What to Compare Before Buying
- Unit model: Confirm that your exact GPS-equipped Humminbird model is supported, particularly if it belongs to the 600-1100 Series.
- Waterway coverage: Check that the lakes you need are among the card’s covered waters in the five listed states.
- Map detail: Consider whether aerial imagery, depth contours, adjustable shallow-water shading, and water-level synchronization match the map information you want to view.
Before You Decide
Confirm the exact unit model and the lakes you need, then check that the Micro SD card format and included adapter suit your intended setup. The listed lake totals describe coverage across the edition, not coverage of every lake in the region.
