Best Trolling Motor and Fishfinder Combo | Top 3 Recommendations

Technology for today’s angler has come a long way from the ole’ rowboat with a can of freshly dug up worms. Using GPS (global positioning system), trolling motors and fish finders can work together to give an angler a handful of features.

Features that allow the angler to focus on fishing rather than steering the boat. So, what is the best trolling motor and fishfinder combo? A trolling motor fishfinder combo works best when the manufacturers work together to create easy and seamless operation between the trolling motor and its paired fish finder.

Here are our top three recommendations for the best fish finder and trolling motor combo.

 How Is Pairing a Trolling Motor to a Fish Finder Beneficial?

The first and most apparent reason for pairing a trolling motor to a fish finder is the hands-free capabilities it will create for you. Spend more time casting, jigging, trolling, changing lures, tying lines, and cutting bait. Normally, you might have to have one hand on the trolling motor’s tiller handle or one foot on the foot pedal control switch to steer and control your boat’s speed.

Either way, you have to be constantly thinking about your position, what is around you, and how you need to adjust to maintain the route you want or to get to the fishing spot you desire.

Next, a fish finder and trolling motor combo that can connect to each other and share data will add a lot of high-end functions and convenience. No messy wires are one of the conveniences that can make your life easier. When you add a transducer to the bottom of your motor you will need to run a wire from the bottom of your motor to your fishfinder. It can be challenging to keep the wire out of your propellor and your stowing mechanism.

With a fish finder and trolling motor combo that utilizes GPS technology, you can free yourself from needing to be in constant control of the boat by inputting routes for your boat to follow. You have many options when charting routes.

First, you can manually enter the route, waypoints, and spot-locks. Second, you can program your trolling motor to follow depth contours and shorelines or use live maps to follow certain seaweed lines or drop-offs.

Either way, your trolling motor will follow the path accurately and will allow you to focus on fishing. Find a honey hole where you keep hitting on nice fish? Then drop a GPS anchor point that you can lock on for that day and save it in your fish finder so you can return to it in the future.

Another benefit of a trolling motor fishfinder combo is it makes it easier to fish with kids. We all love to share the joys of fishing with our children, but there are some challenges, to be honest.

Shorter attention spans, restlessness, and boredom can work together to require our attention constantly. This is another reason to leave your motor’s steering and speed control in the hands of the GPS and fishfinder motor combination.

Who Are the Major Manufacturers Who Produce Trolling Motor Fish Finder Combos?

The major manufacturers who produce the best combos are some of the industry’s biggest names—familiar names like Minn Kota, Humminbird, Garmin, Lowrance, and Motorguide. Minn Kota, Garmin, and Lowrance have the added benefit of manufacturing both the motor and the fish finder.

Minn Kota has partnered with Humminbird to make an equally powerful combination. Whichever you choose, you can be confident that you are purchasing equipment from the most highly respected and trusted brands on the market. 

You could spend hours researching which trolling motor brands pair well with which fish finders, but we did that for you. Here are our top three combo recommendations for 2020.

Motorguide does not make fish finders, but their XI3 Wireless Saltwater trolling motor is still a great motor to consider. The motor is wireless and comes with a small wireless remote with built-in Pinpoint GPS navigation.

The Pinpoint GPS anchor feature will hold your boat in place without deploying your anchor. Click a button when you find a good fishing spot and lock-in. You can then set up a radius for you to maintain with your anchor point.

Powering Your Fish Finder

Many times you will need to power your fish finder from a different power source because of voltage. We are starting to see many people with multiple fishfinder head units use a separate battery to power them. One large benefit is the peace of mind that you don’t need to worry about draining your main motor battery. Dashboard solar panels are a great way to recharge your battery during your fishing day.

So back to the original question, what is the best trolling motor and fishfinder combo? The answer is it is up to your preference. Each trolling motor fishfinder combo has its own set of pros and cons. However, make sure you know which combos are designed to interact with each other.

With Minn Kota, their fishfinder and trolling motor combo works with Humminbird. Garmin and Lowrance manufacture both trolling motors and fishfinders so they naturally can be paired together with their brand. Whichever combination you choose, you will be happy with how the combo will free up your time to focus on fishing rather than navigation.

Can different brands of equipment work together?

Typically one brand of equipment can only work within its own brand of products, but there are some exceptions. Commonly the computerized equipment like chart plotter/depth finders communicate in a system called NMEA 2000 however that doesn’t mean that the data sent through that protocol will be understood by the other devices. Normally basic model transducers can use a conversion cable to be interchangeable. Also, Motorguide makes an effort to produce the largest number of connectors and adaptors for other manufacturers’ equipment.

What brand of fishfinder or chart plotter will work best with my Minn Kota trolling motor?

Humminbird brand fish finders and chart plotters have partnered with Minn Kota to connect easily to all Minn Kota trolling motors that contain i-Pilot technology.

Is the GPS built-in to my trolling motor also used, or is it only the GPS in the fishfinder used?

When you couple together a GPS enabled trolling motor and a fish finder, the GPS systems in both devices are used and communicate with each other. The fishfinder GPS communicates with the trolling motor GPS to relay coordinates and route information. The motor then uses its built-in GPS to steer the motor in the correct direction to complete the route or go to a designated waypoint.

Is it better to purchase a trolling motor fishfinder combo manufactured by the same company?

You may want to purchase a trolling motor and fishfinder manufactured by the same brand, and that is great. However, it is unnecessary to buy in a combo if the trolling motor and fishfinder were designed to interact. For example, Minn Kota and Humminbird are intended for each other.

Can I upload lake maps to my fish finder trolling motor combo?

Yes, most chart plotters and fish finders can connect wirelessly to your laptop or mobile device, and you can download and upload premium lake maps to your chart plotter. Brands like Garmin will have thousands of lake and river maps already preloaded onto your chart plotter. It will then update the maps using sonar to detect changes in depths and underwater structure.
