Even if one portable fish finder review has sparked your interest and you may have found your favorite unit, you should still know what to look for in such a unit. Maybe you will want to look for these devices yourself and make comparisons before you spend money on one. Having said that, here are some things to pay attention to when buying a portable fish finder.
The brand may not be the most important feature, yet it’s still worth considering in some cases. Some brands have experience with such devices, and they know how to manufacture them properly. Not to mention that particular brands may have their own, specific features that make the fish finder accurately detect fish at different depths.
As such, you can pick between a HawkEye, Humminbird, Garmin or Lowrance portable fish finder, and thus end up with the one that serves you properly. When you’re in the market for a fish finder, it’s always best to research the brands you stumble upon.
Although many fish finders do great with just sonar technology, sometimes it’s better to have an additional mapping feature to make sure you know what route you’re taking. While they may be a little pricier, GPS fish finders will be a blessing, especially if you tend to fish in various locations and look for new ones all the time.
What’s also cool is the fact that you can save the position through GPS too, so it’s easier to find it next time you return.
With portable fish finders, you have different types to choose from, depending on which one is more convenient for you. For example, you can choose between mountable fish finders, which can be semi-permanently mounted on your kayak or boat. They cannot be mounted if you’re fishing on the shore, though.
Portable units are the most common models. Although they can be quite large, they are still lightweight enough to maintain their portability. They don’t need to be mounted because they can be held in your hand.
The last type is castable fish finders. These are a little more futuristic and they use WiFi or Bluetooth to connect to your phone. Because they are so small, they are easy to carry with you wherever you go.
Since you’re taking these fish finders outside, it’s essential to have batteries that last long enough. You can choose between disposable or rechargeable batteries. Some can be plugged into a 12-volt power source on a boat too, but that makes them less portable. Rechargeable batteries are the best choice because you don’t have to always spend money on new batteries.
Make sure you choose a fish finder that is waterproof. Not all of them are, and you risk ruining it if water gets to the LED screen. Even if it’s pricier, it’s best to look for a waterproof unit.
