Exploration probe module and premium CHIRP
- Premium remote network probe solution
- Includes real 1 kW two-channel CHIRP, in addition to CHIRP SideVü and ClearVü exploration probes to offer the sharpest images in the water (transducers are sold separately)
- Provides professional sport fishermen with exceptional fish search and background tracking options
- It helps to distinguish between small fish and fish very close to key fishing depths
- Depth capacity of up to 1.52 kilometers (5,000 feet)
The GSD 25 premium probe module is a remote network solution that provides exceptional fish search and background tracking capabilities. It offers 1 kW two-channel CHIRP, in addition to Garmin’s CHIRP DownVü and SideVü exploration probes to enjoy the sharpest exploration images in the water. The images sent to the compatible Garmin plotter provide details of objectives so clear and precise that you can distinguish between small fish and very close to key fishing depths of up to 1.52 kilometers (5,000 feet).
CHIRP of 1 kW real two-channel
CHIRP is the most sophisticated probe technology available to users in the field of fishing and navigation. CHIRP is the acronym for Compressed High-Intensity Radiated Pulse. What you will get is a much higher resolution, clarity and sharpness of the objectives than with any other probe system. If you have the real 1 kW two-channel Garmin CHIRP probe as your usual probe, you can adjust the CHIRP frequencies in low/medium, low/high and medium/high to optimize the performance of the probe. The transducer is sold separately.
Exploration probes that offer the sharpest images in the water
By incorporating CHIRP technology into the DownVü and SideVü exploration probes, you get a higher resolution, a better separation of objectives and a greater sharper clarity of the images of the structures and the fish that pass under and on the sides of the boat. Integrated into our new GPSMAP xsv combinations and the GSD 25 premium probe module, it uses a transducer for the traditional CHIRP HD-ID probe and the CHIRP DownVü and SideVü scanning probes. The transducer is sold separately.

FAQs
Use appropriate tie wraps, fasteners, and sealant to secure cables along the route and through any bulkheads or the deck.
Contact Garmin Product Support if you experience difficulty during the installation.
Apply marine sealant after installing cable grommets to weatherproof around the grommet and cable if needed.
The GSD 25 must not be mounted where it can be submerged.
Mounting hardware is included with the GSD 25, but it may not be suitable for every mounting surface. Evaluate if additional hardware is needed for your application.
The GSD 25 should be installed by a qualified marine installer to ensure best results and safety.
Always check what is on the opposite side of the surface before drilling or cutting to prevent accidental damage.
Mount the sounder so that the LEDs are visible for operational status.
