Humminbird 600033-1 AutoChart Zero Line North America Map SD Card
Quick take
The Humminbird 600033-1 AutoChart Zero Lines card is designed to power AutoChart and AutoChart Live mapping on compatible Humminbird fish finders, combining preloaded shoreline “zero lines” with the ability to record depth and bottom detail to the card. It is a strong fit for anglers who want custom lake contours they can move between compatible units. The main caveat is cost and compatibility: it only helps if you have (or plan to get) a supported Humminbird model and you will actually use the mapping workflow.
Pros and cons
Pros
- Preloaded with Zero Lines shoreline data across the U.S. and Canada, including many named and unnamed water bodies
- Supports recording AutoChart Live data (depth contours plus bottom hardness and vegetation) directly onto the card, for later use
- Includes 16 GB of free space for maintaining your custom maps on the 32 GB card
- Lets you view the same custom-made maps on multiple compatible Humminbird fish finders (extra card use)
Cons
- Worth it only if your Humminbird unit is optional/compatible with Zero Lines, and the exact supported models can change
- Buyer feedback highlights that the price can feel steep if you are expecting it to be included with other Humminbird purchases
What buyers think
Available buyer feedback is generally positive, especially for shoppers who want a practical way to navigate and map lakes that may not have detailed digital coverage everywhere. Buyers describe the card as helpful for boat navigation and for getting a more complete “mapped” look on the water when used alongside a compatible Humminbird. Several comments also highlight that the mapping workflow produces useful, on-water reference for regular fishing spots. At the same time, price comes up as the most common hesitation in the feedback, with some buyers feeling it is expensive relative to what they get from a mapping card.
What this card is for
This microSD mapping card (model 600033-1) is built around Humminbird’s AutoChart and AutoChart Live ecosystem. It gives you a starting point with preloaded Zero Lines shoreline information, then allows compatible units to record additional sonar-derived mapping data and save it directly to the card. After recording, you can transfer and display your custom map content on compatible Humminbird fish finders.
Preloaded Zero Lines coverage across North America
The card comes loaded with extensive shoreline data for the U.S. and Canada. That includes over 140,000 named water bodies and over 1.75 million unnamed water bodies in the U.S., plus over 96,000 named water bodies and over 3.85 million unnamed water bodies in Canada. In practice, this is meant to improve how well your fish finder can render lake and shoreline context, even when you are not creating fully custom maps for every location.
Record your own contours with AutoChart Live (compatible models)
If you use a compatible Humminbird fish finder, the workflow is centered on recording directly to the card. That includes depth contours and additional bottom details such as bottom hardness and vegetation when supported by your setup. The card’s built-in storage also matters here: it is a 32 GB card with 16 GB of free space dedicated to maintaining your custom maps.
Sharing and moving maps between fish finders
One practical reason shoppers consider an extra card is flexibility. This is intended to let you create maps and then view them on multiple compatible Humminbird units by using the card as the storage medium for your custom content.
Compatibility notes to double-check before buying
The Zero Lines card is optional for select Humminbird model families, including select APEX, SOLIX, ONIX, ION, HELIX, and some 1100, 900, 800, and 600 Series models. Compatibility can change, so it is important to confirm your exact fish finder model supports this card and the Zero Lines functionality you want.
Pros and cons (in plain terms)
Best for: anglers who want detailed mapping of their local lakes and fishing spots, and who plan to use AutoChart or AutoChart Live to record and save custom depth contours and bottom detail.
May be less ideal for: buyers who only want basic location awareness or shoreline context, or anyone whose Humminbird model does not support Zero Lines and the AutoChart/AutoChart Live mapping workflow.
Price and availability
Pricing can be a meaningful part of the decision for this type of mapping accessory, and some buyers explicitly mention that the card can feel expensive depending on what they already spent on their Humminbird setup. If you are actively mapping and using custom contours regularly, the value tends to make more sense. If you are not likely to record and manage custom maps, you may want to reconsider.
Verdict
The Humminbird 600033-1 is a useful tool for turning your Humminbird sonar and GPS data into custom contours you can carry on the card and display on compatible units. It also adds preloaded Zero Lines shoreline coverage across the U.S. and Canada, which helps make mapping more immediately practical. It is a smart buy when you will genuinely use AutoChart Live-style recording, but it is easier to regret if your model is not compatible or if you mainly want map context without custom mapping.
FAQs
Is the Humminbird 600033-1 AutoChart Zero Line card compatible with all Humminbird fish finders?
No. It is optional for select Humminbird model families (and support can change). Check that your exact Humminbird model supports Zero Lines and the AutoChart/AutoChart Live workflow you want to use.
What does the “Zero Lines” preloaded data include?
It includes extensive shoreline data for many water bodies in the U.S. and Canada, with counts provided for both named and unnamed water bodies.
Can this card record custom mapping data?
Yes, with compatible Humminbird models you can record AutoChart Live data directly to the card, including depth contours and additional bottom details such as bottom hardness and vegetation (when supported by your setup).
How much space is available for custom maps?
The card is 32 GB and includes 16 GB of free space intended for maintaining custom maps.
Does the card let me use the same custom map on more than one fish finder?
That is the idea. It can be used as an extra card so compatible Humminbird units can display your custom-made maps using the card.
Is it worth buying if I do not plan to map my own lakes?
If you only need basic map context and you will not use AutoChart or AutoChart Live recording, this accessory may be harder to justify. It is best when you expect to create and reuse custom lake contours and bottom detail.
