Hummingbird RF35 Watch with Sonar Sensor Fish Locator Wrist Watch

If a radio controlled fish locating boat doesn't appeal but you're
looking for a device to help you locate those elusive fish - thus
ensuring you get your fish supper - how about this (somewhat more
compact) Hummingbird RF35 wrist watch which is aimed squarely at
fisherman and which comes with an advanced, wireless sonar sensor
allowing you to locate your prey in real time with ease via the watch's
1.25 LCD display?

Capable of locating fish at ranges of up to 75 feet and at depths down
to 120 feet thanks to its remote sonar sensor, which offers a 90 degree
sonar beam, the Hummingbird RF35 watch naturally serves as a standard
wrist watch when not assisting you in finding fish and, thanks to its
backlit display, will even doubtless prove invaluable for a little night
fishing.

The Hummingbird RF35 watch with wireless sonar sensor will set you back
just shy of $80 - which makes it considerable cheaper than the
aforementioned (though far more advanced) fish locating boat which will
set you back over a cool $6000.
