Humminbird CoastMaster U.S. Coastal V1 Map SD Card for Fish Finders
Quick take
The Humminbird CoastMaster U.S. Coastal V1 Map SD Card is a mapping upgrade for compatible Humminbird HELIX, SOLIX, APEX, and XPLORE units, giving you more detailed U.S. coastal charts with depth highlights and navigation aids. It is often described as an easy, plug-and-play improvement in map detail, but feature expectations like tides can depend on the specific setup.
Pros and cons
Pros
- Designed for compatible Humminbird HELIX G3/G3N and newer, SOLIX, APEX, and XPLORE units.
- Focuses on practical coastal fishing visuals, including depth highlight ranges and shallow-water red shading.
- Includes mapping tools aimed at planning trips, with tidal direction/height and current info.
- Provides quick switching between fishing charts and nautical chart views, plus customizable palettes.
Cons
- It is a map card, not a “fish finder that finds fish” on its own, so it won’t replace sonar.
- Some buyers report missing or incomplete tide functionality, suggesting you should verify expectations for your exact unit configuration.
- Best value is strongest if you already own a supported Humminbird compatible unit.
What buyers think
Buyer-review evidence centers on how much more useful the display looks after upgrading the built-in map, with several comments pointing to improved detail and a simple installation experience. Users also consistently frame the card as a chart and navigation solution, not a direct replacement for locating fish, which shows up in the way expectations are managed. There is some limited but notable feedback that certain planning elements, such as tides, may not work as expected on some setups.
What this map card is for
This CoastMaster SD card is meant to expand what your compatible Humminbird unit can show along U.S. coastal waters. If you already have a supported Humminbird chartplotter or fish finder, the main benefit is better charts on-screen, including depth-related visualization tools and navigation aids that help you move confidently and target productive areas.
Key features that matter on the water
Compatibility with popular Humminbird lines
The card is built to work with Humminbird HELIX G3/G3N (and newer), all SOLIX units, all APEX units, and all XPLORE units. Before buying, confirm your exact model falls within that supported family so you avoid frustration.
More detailed coastal charts and easier-to-read views
CoastMaster emphasizes chart detail and faster map loading, plus customization through color palettes. It also supports preset view modes, letting you switch quickly between fishing and nautical-style presentation or create your own view settings.
Depth highlights and shallow-water visibility
You can create up to four user-defined depth highlight ranges, which is useful when you know the water depths that historically produce for your fishing spots. The card also supports red shading highlights for shallow water areas on an adjustable range from zero to 30 feet.
Trip planning tools (tides and current information)
CoastMaster includes predictive planning features intended to show tidal direction and height, plus current speed and direction. It also offers contour and shoreline synchronization so the chart reflects the current water level of your fishing spots. Note that some buyers report challenges with getting tides to work, so it is worth verifying those expectations for your specific unit and configuration.
Navigation aids, reefs, and points of interest
Beyond fishing-oriented visuals, the card provides navigational data such as navigation aids, artificial reefs, and points of interest. That can be particularly helpful when you are exploring new areas or returning to familiar spots and want supporting context on the chart.
Pros and cons, from a buyer’s perspective
Good fit if you want better coastal mapping on an existing Humminbird unit
- You fish or navigate in U.S. coastal waters and want depth-related charting tools that help you interpret locations faster.
- You prefer simple upgrades, since buyers commonly describe the card as straightforward to use.
- You want planning support like tidal direction/height and current info, alongside navigational references.
Not the best choice if you expect “fish detection” from the SD card
- If your goal is to locate fish directly, remember this is a chart/map SD card. Sonar performance and how your Humminbird unit interprets returns are still what ultimately tells you about fish.
- If tides and water-level synchronization are a must-have, confirm compatibility and feature availability for your exact setup. Review feedback suggests this area may not work the same for everyone.
Is it worth it?
The CoastMaster U.S. Coastal V1 Map SD Card is typically worth considering when you are already invested in a compatible Humminbird ecosystem and want clearer, more detailed coastal charting than standard base maps. It is especially compelling if you like depth highlight ranges, shallow-water emphasis, and navigation-oriented context. If you specifically rely on tides showing accurately, validate that your unit’s configuration supports those planning features before you commit.
Price and availability
Pricing varies by retailer and can fluctuate. Availability may change quickly, so if you see limited stock, check the current price and shipping details before ordering.
FAQ

Will this SD card tell me where fish are?
It is a mapping upgrade that improves charts and fishing-related visuals. It does not replace sonar. Use it to interpret locations, depth ranges, and navigation context, while your sonar still handles fish detection.
What depth features does it include?
You can set up to four user-defined depth highlight ranges, and it includes red shading highlights for shallow water areas from zero to 30 feet (adjustable within that range).
Does it include tides and current information?
CoastMaster includes predictive planning tools for tidal direction and height, plus current speed and direction, along with shoreline and depth contour synchronization to reflect current water levels. Some buyers report that tide behavior may not match expectations on all setups, so verify compatibility with your unit.
What’s included in the box?
The package includes a Micro SD card, a Micro SD card adapter, and a quick start guide.
