If you’re looking for a simple device to help you navigate from A to B without the complexity of a more expensive system, the Garmin GPS 73 handheld marine GPS device might be the right one for you. Its intuitive user interface with dedicated backlit buttons make it simple to adjust and get to know the system without too much onboarding.

The device also includes SailAssist technology, which helps you sail more effectively with a heading line and tack assist. Tack Assist will let you know when to tack based on whether your boat is getting headed or lifted compared to the boat’s optimal tacking angle.

Finally, this device is powered by Double A batteries. Though it may seem analog, when you’re out on the water and the batteries fade away or if you have a boat without power, all you have to do is replace the batteries to use the device instead of waiting for it to charge.



Most GPS units are pre-loaded with a “basemap” with varying levels of detail. Basemaps show crude or blocky representations of geography. Many of the newer devices allow for the use of micro SD cards that come pre-loaded with more detailed maps. When you’re traveling to new locations, you can purchase new micro SD cards that correspond with your destination and region. You’ll want to make sure that you’ve pre-purchased your maps before heading out on your expedition.


If you enjoy other activities that require road, trail, or fishing trips, then you might want a GPS unit that is also compatible for these types of adventures. When you’re deciding on your purchase, you’ll want to make sure that your GPS can come with you on all of your adventures. For more information about how to choose the best GPS for you, check out this article about choosing the right GPS device for you.


A marine handheld GPS device with WiFi interface capability will allow you to download maps directly from the Internet without having to connect the device with a cord and USB. It’s also a handy way to share your waypoints back and forth with another device. For more information about GPS device features, check out this article on choosing the right GPS receiver for you from West Marine.


The value of a marine handheld GPS is that it’s safer and more durable than your smartphone. And with the added value of a touch screen or sonar capability, you’ll be traveling with an incredibly powerful location device. Sonar uses sound to understand the geography of what’s going on under the water. Ultimately, you’ll have to decide what type of device will work best for you and your adventures.
