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.
It is a budget model. This is the bare-bones version of more expensive Garmin fishfinders for those with limited budgets. This is a great option for anyone looking to get into fishing tech, even if it's not the most expensive.
The two most popular types of a GPS fishfinder combo are fixed mount or portable. Portable versions can be mounted on a boat's transom or mounted using suction cups. An alternative is to attach the fish finder GPS combination to your smartphone, tablet, or other device. Transducers comprise the bulk of a GPS combination fish finder. These emit and receive sound waves that are then converted into images on a screen.
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 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.
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."
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.
