There’s now supposedly an app called Deeper Smart Fishfinder that can
help you catch fish, but it hasn’t been commercially produced yet. It
makes use of a separate floating device, which is a 6cm diameter sphere
that will be paired with a user’s Android or iOS device to let him or
her know if there are any fish in the area. Users can even attach their
fishing line to one of these.
The device emits ultrasound waves down into the water to provide data
on the location and number of nearby fish, as well as things such as
depth and temperature of the water. This information is then transmitted
via Bluetooth up to a distance of 50m to the user’s mobile device. When
the user catches a fish, they can use their phone or tablet to take a
photo of the fish and post it onto Facebook or Twitter, all while
remaining within the app.
The Florida-based tech company Friday Lab is currently working on a
prototype and raising funds in hopes to sell them to consumers at a
price of US $199.
