Things to Consider Before Buying the Best Fish Finders Under $500
A fish finder can make or break your day on the water. Between different brands and technologies, there are plenty of options available. Knowing which ones suit your needs will optimize performance and save you money on unnecessary features. Fish finders should have easy-to-use imaging, solid mounting hardware, and trolling motor compatibility. Units that check these boxes cut down the learning curve on new water bodies and put you on fish.
Finding a unit that is user-friendly with a variety of scanning options is a must. To start, any fish finder on my boat must have satellite maps. This is crucial to find your way around new water bodies or keep you from getting lost when there’s no service. Features like sonar, down imaging, and side imaging work great for locating fish. The combination of these three allows anglers to see what is around the boat and under it.
Look for units with metal mounting brackets when possible. Other good options are swivel mounts that allow you to manipulate the screen. Bass anglers have even gone as far as developing special mounting plates to keep all their screens secure in rough water. Whatever you go with, make sure it can withstand the conditions you plan on using it in.
Trolling Motor Compatibility
Fish finders that are compatible with your trolling motor can unlock useful features. With spot lock compatible motors, you can drop a pin or draw a track and your trolling motor will follow it. When I find a school of fish or a particular piece of structure, spot lock keeps me dialed in. Not all trolling motors are compatible with all fish finders, so be sure the one you choose will work for your motor.
Q: What is the simplest fish finder?
The easiest fish finders to use are sonar units. These fish finders only scan the bottom and ping back fish below. Without any other features, these units are ready to go out of the box. For anglers, this is an easy way to see depths, bottom structure, and fish. Target the drop-offs and fish will be hiding just off ledges waiting to ambush prey.
Q: Do all fish finders have GPS?
Not all fish finders have GPS. While most models available will have some sort of navigation features there are basic options available. The basic units come with sonar to mark fish and structure. They are easy to use and cheap compared to other models. Anglers just starting or fishing smaller water bodies can familiarize themselves with fish finders for a minimal investment.
Q: Is a fish finder and a depth finder the same thing?
Modern fish finders and depth finders are not the same things. They both work by sending a signal downwards that reflects back. When a fish is in the signals path it shows up as a U-shaped mark on a fish finder. Depth finders use this same process but instead read the time it takes for the signal to return. These are great for offshore fishing and can find deep canyons or drop-offs where pelagic fish may hold.
Q: How deep can a fish finder go?
It depends on the model of the fish finder and transducer but some can read as deep as 400 feet. In that range depth finders mark fish best in 200 feet of water or less. For anglers wanting to see deeper, a depth finder can be used. Depth finders can read thousands of feet deep. Unfortunately, they do not mark fish but can help anglers locate likely spots where fish should hold.
Final Thoughts on the Best Fish Finders Under $500
Fish finders are great tools for anglers on the water. When dialed in properly, they can give you an edge over other anglers. Look for units with features you want, that are easy to use, and durable. While fish finders will help cut down the learning curve there is no substitute for time on the water. Choose something that fits your boat and your style of fishing and spend some time using it.
