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.

Luxurious looking watch for great price
The watch is simple yet, it looks expensive. The material of the watchband is high quality and holds its shape well.

Stunning automatic watch — looks way more expensive than it is
Color: All Gold, Color: All Gold
I bought this OLEVS automatic as a gift for my husband and he was thrilled. The gold-tone finish is rich and consistent, the open-heart dial showing the movement is a beautiful touch, and the day/week sub-dials work smoothly. The caseback shows the automatic movement clearly — you can see the rotor spinning with every wrist movement. It feels comfortable and the bracelet is solid. For the price, this is an outstanding piece. He gets compliments every time he wears it.​​​​​​​​​​​​​​​​
