Transducer Downrods
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.
Telescoping
The Telescoping downrod is used exclusively for Down and Side View transducers. These transducers have cable connectors that are smaller than those used for scanning sonar transducers. This means that we can run side view transducer cables inside the sliding tube of a telescoping downrod.
Telescoping Downrods use a reinforced nylon tube collet to hold the lower 1-inch tube. The sliding tube can be set anywhere between 26 inches and 48 inches in length.
Solid Downrods for Live Scanning sonar
Solid length downrods are 1 1/2 inch OD to allow for the larger connectors of Scanning sonars to fit inside the downrod. Running cables inside of downrods helps to protect the cable and prevent sheathing damage. It also means that you can never wrap the cable around the downrod. It also prevents catching the cable with an errent fish hook.
These downrods start at 48 inches in length and can be extended up to 72 inches for deep draft boats.
Which One?
Telescoping is used only for Side view and down view conventional transducers.
Solid downrods are used specifically for live scanning sonars.
A NOTE ABOUT TRANSDUCERS AND DOWNRODS
Humminbird
Most Humminbird transducer cables utilize a compact connector. As such, these transducers can be used with the 1 inch OD tubes or telescoping tubes without any modification or change
Humminbird Solix must use a larger diameter downrod (1.25 inch OD) for their systems.
Lowrance
Lowrance NEW HOOK2 series transducers use a new connector style and will fit in 1 inch downrods. As such, 1″ OD tube or the easy to use telescoping downrods are ok for these units.
Lowrance HDS Structure Scan, Total scan transducers utilizes a large thumbscrew on their connectors. This thumbscrew is slightly larger than the ID of a 1 inch tube. The connector itself can be modified to fit a 1 inch tube. AS shown in the photos, sanding of the nubs on the connectors will allow them to easily fit through a 1 inch tube making it an option for anyone wishing to do this slight modification. This minor modification allows Lowrance users to also utilize the telescoping tube or 1 inch OD solid.
Lowrance 3D transducers use a dual connection. This is so large that only a 1.5 inch OD tube can be used. Please call to discuss.
Garmin
LIVESCOPE: Due to the size of the Livescope connectors, a 1.5 inch dia downrod is required. Please order the specific Livescope Bowducer system for these transducers.
Garmin SI and DI Transducers all fit within a 1 inch tube so like Humminbird, any downrod style is acceptable and the telescoping downrod is a great choice.
