COROS HYDROP

A castable fishing sensor that reveals the underwater environment to help you catch more fish

MEET YOUR NEW UNDER WATER SCOUT

Fishing is often a sport of what-ifs. What if the water is colder ten feet down? What if that drop-off is deeper than it looks? COROS HYDROP is a new fishing sensor that provides the data you need for a more informed cast.

LEARN MORE ABOUT THE WATER

HYDROP packs advanced sensors into a tiny, rugged capsule that talks directly to your COROS NOMAD. It's easy-to-use set-up means that you'll gain more information to help you fish better from the first cast.

STAND OUT IN THE WATER

Using optical sensors, HYDROP measures transparency and identifies the water's true color profile. It tells you exactly how much light is penetrating the depths so you can pick the lure color & the lure size that will actually pop.

SEE THE FLOOR

HYDROP maps out the water below with total precision – identifying drop-offs, hidden ditches, and submerged timber where big fish stack up, giving you a clear map of the strike zone.

HUNT THE THERMOCLINE

Fish are picky about temperature, and the surface temp rarely tells the whole story. HYDROP tracks water temperature vertically as it moves through the depths, helping you find that "golden" layer of water where the fish are actually active and feeding.

LIGHTER THAN YOUR FAVORITE LURE

Weighing in at just 10.6 grams, HYDROP is lighter than a standard half-ounce spinnerbait, meaning you can cast it with the gear you already own without worrying about straining your line or your rod.
