Deeper Start smart fishfinder, Wi-Fi, 50 m cast and depth

The Deeper Start is a castable fishfinder: tie it to your line, cast it out and see depth, bottom and fish on your smartphone or tablet. It connects over Wi-Fi — which the maker says is steadier and up to 10 times faster than Bluetooth — and takes 10 scans a second.

It switches itself on in the water and off when you take it out, and a built-in LED lights up automatically. Every scan is saved and can be viewed later in the app or online in Lakebook. A magnetic USB charging cable is included.
