Okay, to make the Humminbird line even better, now you can mount your fishfinder right to your fishing rod. Really, does it get much simpler than that? It's perfect for you if you can't attach a fishfinder to your kayak or fishing tube, or you are fishing from the bank. We don't think you'll find an easier way to cast your line and see where it lands than by using the RF 20. It allows you to use your hands while you watch what's happening below the surface. This could be one of the best features you can have on your fishing rod. Let's take a look at the features that it offers you.

The RF 20 uses Remote Sonar Sensor (RSS) technology. This is one of the most effective means of knowing what is under the water as well as know what's out ahead of you. This is helpful because it allows you to know just where you need to go to get your fish. Should you cast straight ahead or should you go slightly to the east? You can cast upto 100 feet from your boat or the bank, and it will read upto 100 feet in depth. Then reel it back in. Or attach your bait to the RSS and get a real-time view of what's happening to your cast. This is superb for getting a good look at what's below and what's far out.

You get One-Touch menu navigation to your tools such as FishID+, depth range, fish alarm, and sensitivity. This provides you with simplicity in that you can easily move through your needs while keeping one hand on your line. As for the sonar, you get ultra wide sonar coverage that is equal to twice the water's depth. This is important as you need powerful sonar to see what's below you. This gives you the ability to know where to cast and what to use as bait.

As for the display, we think you will be impressed by the RF 20. It has a high visibility 1 ? inch diagonal display with 48V by 32H resolution. The RF 20 has 100 feet in remote operation range and 100 feet in depth capability. This translates into some nice range that will allow you a good idea of what's lurking out there. You get a clear, easy to read digital depth display as well. It includes one waterproof A channel RSS. Get this out there and it will transmit back to you what you need to know! We think that this RF 20 is an excellent option for the fish finder!
