  • Add the MSC™ 10 external satellite compass (sold separately) to eliminate wave and swell from your sonar returns with heave compensation
  • Compatible with a wide range of Garmin and AIRMAR® transducers (sold separately)

The depths. Revealed. Take your sport fishing to extreme depths with GSD™ 28, a high-powered sonar module with features to improve your chances for success (transducer-dependent). Garmin RapidReturn™ sonar provides quicker returns on your chartplotter with 2 to 6 times the ping rate of our GSD 26, so you see fish before you’re out of range (transducer-dependent). Easily distinguish bait from sport fish, and get our clearest sonar with next-generation xCHIRP technology. GSD 28 supports a wide range of Garmin and AIRMAR® transducers (sold separately) that can be manually or automatically configured. When the seas get rough, ensure flat bottom returns with the MSC™ 10 external heave compensation sensor (sold separately).

The GSD 28 module is ideal for retrofitting to boats with existing bare wire transducers.

Extremely thin material.
Size: 34W x 32L, Color: Midnight Selvedge
Really thin material. For the price I was expecting something closer to a buck mason quality fabric but these jeans are extremely light weight and I don’t expect them to last.

Denim feels thin but soft
Size: 32W x 32L, Color: All My Days Selvedge
The denim seems thinner than from years ago. 100% cotton feels soft. Fit me same as other stretchy 505 that are made with elastine. Waist size is fine. Haven't washed them yet. Yes, the price is high, but I like the 100% cotton and will likely buy more selvedge jeans.

100 cotton
Size: 33W x 32L, Color: Midnight Selvedge
These are great, just keep in mind that 100% cotton is not the same as 99 cotton 1 elastane, so size up if you tend to be in between mesures at waist.
