Attaching the RSS, RSS Power | Humminbird RF20 specs

Handle the RSS by the antenna tower when it

has been in water.

Use a heavy test line, standard knots, and tackle such as a swivel.

The second leader hole is for using the RSS as a float. Connect a lighter weight hook line to this hole. Do not over-weight the hook line as this will submerge the RSS, causing signal loss.

Attaching the RSS

The line coming from your reel can be tied off to the front hole in the Remote Sonar Sensor (RSS). If you also wish to use the RSS as a con- ventional float, use the second hole to attach your hook using a lighter weight line. A snag will break the lighter line if you have to break free. Slip line techniques are not recommended because of the higher risk of losing the RSS. If you do use the slip line method, use a lighter weight line after the lower stop, enabling retrieval of the RSS if the lower line with hook breaks away.

CAUTION: You will increase the possibility of breaking your line if you use light test pound line on your reel. The RSS is positively buoyant (is buoyant under its own weight plus 0.2 ounces or 5.7 g of bait and lead weight.) The maximum amount of weight for any attachment to the RSS is approximately ¹² to ¹³ ounces (5.3 g to 5.8 g), and includes the combined weight of any hook, line, weight, swivel/snap swivel and bait that is attached to the RSS. The RSS itself weighs 1 ounce (28 g), and therefore light test line might break.

NOTE: Store the RSS in a dry, non-metallic container, such as a tackle box, in a separate compartment, and isolated from any metallic devices.

RSS Power

The Remote Sonar Sensor (RSS) has a separate, non-replaceable lithium battery that has a shelf life of three years and will last for approximately 400 hours of in-water use. Discard the used RSS in compliance with local laws as you would any electronic component or battery.

The RSS will turn on its Sonar Transmitter/Receiver automatically when it is immersed in the water. Once immersed, the RSS will begin transmitting the sonar information via radio frequency (RF) to the Rod Mounted Display. The RSS auto- matically stops using power a few seconds after being pulled out of the water.

WARNING! Do not place the RSS in a wet area when not in use as this will turn on the RSS and shorten its usable life. Store the RSS in a dry area when not in use to conserve power. Never place the RSS in a wet area of a boat or on a metal surface that could accidentally power it on.

NOTE: If the RSS was used in salt water, rinse it with fresh water before storing it.

What’s On the Display

The SmartCast displays under-water information in an easy to understand format. The top of the display corresponds to the water surface, and the bottom of the display corresponds to the selected Depth Range (see Depth Range). The display varies as the area under the RSS changes.

Underwater conditions vary greatly, so some experience and interpretation is needed to realize all the benefits of the SmartCast – use the diagram as a guide to the most com- mon conditions and practice using the SmartCast over known bottom types.

RF20 specifications

The Humminbird RF20 is a robust and versatile fish finder designed for anglers who seek to enhance their fishing experience on both freshwater and saltwater. Known for its advanced technologies and user-friendly features, the RF20 is a standout device in the marketplace.

One of the main features of the Humminbird RF20 is its dual beam sonar capability, which offers a wider coverage area and improved fish detection. Users can select between a narrow beam for precise imaging of underwater structures and a wider beam for covering larger areas. This ability to switch between beam widths makes it easier for anglers to locate fish in various environments.

The RF20 is also equipped with advanced GPS technology, providing accurate location data and mapping capabilities. With high-definition mapping, users can view detailed contours of lakes and rivers, allowing them to plan their fishing strategies effectively.
