The Echo 301dv is a fish finder that uses sonar technology to detect both aquatic life and other materials both in shallow and deep water.
It has a 3.5” display screen with a backlight feature and 300W power capacity. Garmin has come up with a new feature in this device, and that is the Smooth Scaling graphics feature.
It is very economical and with this price, you cannot expect anything more. The DownVu sonar technology that it offers has the capability to reach depths of 1,750’ maximum.
Though there are more expensive alternatives available on the market, the Echo 301dv makes the perfect choice for those with a limited budget.
