Deeper is a gadget that turns your smartphone into a sonar device that can spot fish.

The wireless device connects to your smartphone via bluetooth and relays such information as the location of the fish, its depth, and the likely species, as well as water temperature, bottom contour, and more.

Deeper is lightweight, meaning it won’t be hard to load it up with your other fishing gear. It simply attaches to the boat or a fishing line.

Deeper is compatible with both iOS and Android devices and is currently available with a price tag of $199.
