Fishfinder GPS Combo Reviews – Best Value for the Money
Fishing tech has come a long way in the years since I saw my first fish finder. I can still remember seeing the big and small fish icons on the viewing screen and, as a kid, I was certain there was a man-sized fish directly under the boat! Well… it never seemed to help me much, but these days the sonar and depth imaging technology has come so far that it’s really possible to up your game with a nice fish finder. On top of that, we’ve now got access to great geolocation technology (GPS) at reasonable prices. Combo units gather location data and merge it with underwater imaging data to create a holistic picture of where and what you’re fishing!
Benefits of GPS Fish Finder Combo Units
For most open water or deep water fishermen, a GPS unit is a must-have. As soon as land is out of sight, navigation becomes a real issue as everything looks the same. Even for experienced fishermen in large lakes or bodies of water, it can be difficult or impossible to get back to your favorite spot every time.
When using a GPS combo unit, not only can you navigate accurately and quickly to great fishing spots, but you can save and locate multiple spots later. You might not fish a certain area for months or years at a time, but when it’s time to head back you’ll be fishing the same area with precision. Combo units also allow you to gather data about water conditions, depth, and schooling behavior in combination with location.
To top it all off, using a combo unit will result in less overall clutter and gadgetry which can get in the way, break down, or use up energy from the boat. If you’re going to be using a GPS and a fish finder, there’s really no reason to use separate units. If for no other reason than simplicity, they just make sense.
How to Choose a GPS Fish Finder Combo Unit
Frequencies: Fish finders may operate under a range of frequencies when scanning and locating underwater objects such as surface features and fish. Advanced fish finders may even be able to send and receive multiple frequencies at the same time. Why is frequency such a big deal? Because higher frequencies yield greater detail but fail to work in deep waters. Lower frequencies carry further but yield less detail on the screen.
If you’re a shallow water fisherman, a high frequency output is in your best interest and will yield the best results. If you’re a deep water or commercial fisherman, a low frequency emission is probably the better choice.
Power: Fish finders operate under a wide range of power output measured in watts (W). Higher power output means better and deeper readings. Lower power units won’t be able to send readings out as far and the images received will be significantly poorer quality when compared to higher power units. When you combine the power output and frequency output of your fish finder, you’ll have an overall understanding of the unit’s ability.
A low power, high frequency unit won’t be able to scan very deeply while a high power, low frequency unit will scan very deeply. Remember, this is a balance between your needs for depth, power, and image clarity.
Visual Display Considerations: When choosing a GPS fish finder unit, you’ll definitely want to spend some extra money for a decent screen. Because your screen will often serve double duty as GPS, fish finder, or even split-screen fish finder (dual frequency) it’s critical to have a large enough screen with good color and resolution.
Since most readers will likely purchase the GPS fish finder combo unit as their main screen, it’s pretty important to go for the largest and highest resolution screen size that your budget will afford. This will give you the ability to use split screen functionality, color variance, and easily spot, mark and navigate with the unit on the fly. Without a doubt this is one of the biggest overall factors which will impact your long-term enjoyment of the unit as a whole.
