The 5” display screen of the Garmin Echo 551dv features a modest 480x640 pixel resolution. It has a VGA colour display that provides crisp images that will allow you to make out specific details of the underwater structures. This fish finding device gives you the option of viewing the output on the split screen both vertically and horizontally. You can also zoom in to get more details on the sonar.
We definitely like the smooth scaling technology as this feature makes transitions perfectly scaled – no matter if you are in deep or shallow waters.
With both the DownVu and traditional dual beam sonar, the high 500W power output allows the sonar to reach large depths. Its capability is 2,300 feet – making it ideal for deep waters fishing. The DownVu provides photo-quality images of the fish and structure located underneath the boat.
The dual-beam transducer comes with two options: a low frequency 77 kHz sonar mode and a high frequency 200 kHz sonar mode. The low frequency is used for the wide general view. The high frequency is for more defined and accurate results. The downside is that they can’t dig as much depth as the lower frequency son, making them more effective in shallow water.
This unit also comes with HD-ID technology with DownVu integration. This means that you can view fish as icons or as raw data. The DownVu sonar is highly accurate as it sends and receives sonar waves for an accurate image of what’s under you.
Various Mount Types
To ensure that your investment is worth the price, you will need a fish finder that has a mount for your watercraft. If by chance you use several different models of craft, you will definitely need multiple types of mount. The Garmin Echo 551dv comes with three mount types – the trolling motor, transom, and the tilt/swivel quick-release.
Most fishermen already know the importance of knowing a wide variety of information at once. With the dual-view monitor feature, this is extremely useful as you can easily access multiple screens at the same time.
This will benefit your fishing experience as you get to view more technical aspects, which sets this model apart from the rest on the market. We definitely like this feature as you can spend more time trying to catch fish instead of constantly switching between screens.
The Garmin Echo is IPX7 waterproof, which means it will resist the rain, incidental water spills, etc. While it’s not completely waterproof, it is best to avoid it being submerged in water, especially salt water.
