The best part is that you can use the GPS to track your location and chart waypoints. You can also create maps of all the lakes in your area. It's almost like bringing a treasure map to the water. Start your trolling motor and set it low. You'll be amazed at the best GPS fish finders available.
You can also create maps and contours. By creating travel paths, you will be able to create a plan every time you go to fish a specific lake. You will be able plan using data from your previous trips.
The screen size does not always have to be the deciding factor in choosing a fish finder. For those fishing from smaller boats or kayaks, I think the smaller screen is a benefit. It is easier to mount and operate than equipment with 12-inch screens.
Let me first address the elephant. So this fish finder does indeed have GPS and mapping but no MicroSD slot. This means that the Garmin maps you get with your fishfinder unit are all you have.
Although all of this can seem overwhelming, the good news is that you have the option to choose which features you would like since each one has a dollar sign attached. I should start a store called "Build a Fish Finder."
The GPS feature offers 2,500 waypoints, 45 routes and integration with AutoChart or Live Navionics. These are premium upgrades and will almost always cost more.
Mega+ down imaging and side imaging are available. This is basically saying that you can see more detail than most fish finders. 360-degree imaging is the best sonar feature. This unit can provide you with a 360-degree view from up to 125 feet away from your boat.
