Find out what’s in the background. Capture what’s in the background. Practice sport fishing at extreme depths with a high-power probe module with the functions you need to increase your chances of success.
Garmin rapidreturn probe
This high-performance technology provides our traditional deep-water probe faster, with a ping rate of 2 to 6 times higher1 than that of our GSD™ 26 probe. This allows captains to make quick and informed decisions based on what is under their boats.
Xchirp technology
Easily distinguish the bait of the fish with the fish bows and the excellent separation of the objectives of our sharpest traditional probe. Get smooth background returns and precise objectives at extreme depths1.
Arfada compensation
When the sea is rough, use the MSC™ 10 satellite compass (sold separately) to greatly reduce the waves and increase the returns of the probe.
Compatibility with transducers
This probe module is compatible with a wide range of Garmin and AIRMAR® transducers (sold separately).
Adaptation
The GSD 28 module is ideal for adaptation to boats with existing bare cable transducers.
