PcFF80 PC Based Analog and DSP Color Fish Finder for Windows

The PCFF80 is a full-featured dual frequency high resolution PC based color fishfinder runs under windows 98, NT, 2000, XP, Vista, Win7 and Win10 in both analog and DSP mode (Digital Signal Processing).

Turn your laptop or desktop computer into a full-color fishfinder with a huge display screen and save thousands of dollars. Compare the cost and resolution of the PcFF80 full-color 1024 x 768 pixel display screen with that of fishfinders costing as much as US$6000.

Unlike a standard fishfinder that is born with all the capability it will ever have, the PcFF80 PC Fishfinder can be updated via just a software change and will never go obsolete.

The PCFF80 system consists of a high speed Interface Box, a program CD, dual frequency 50khz/200kHz depth/temperature transducer and a printed user's manual. The user's manual is also available on-line (included on the CD in PDF format).

Communication to the Interface Box is through either a high-speed RS-232 port or USB port (both modes are supported).

The depth/temperature transducer plugs into the interface box which contains the Signal Processing unit and sonar transmitter/receiver as well as temperature measuring circuitry. The Interface Box is powered with +12VDC through a 10 amp fuse.

Analog and Digital Signal Processing - the best of both worlds: The 50kHz/200kHz dual frequency depth transducer provides for the best resolution and definition of features at 200khz in analog mode to depths of 500 feet and uses Digital Signal Processing to reach deeper depths of 1000+ feet at 200Khz not possible with normal analog processing. Switch to 50Khz to go even deeper and use both 50Khz and DSP to achieve maximum deep water performance.

The extra processing power of the DSP and your computer enable the PcFF80 to reach deeper depths without reducing the frequency and without loss of resolution. You will be able to see smaller object in deeper water using DSP because you can continue to use the higher resolution 200Khz frequency before having to switch down to the 50Khz frequency.

AT 200Khz you can see small baitfish you would miss completely when using 50Khz. Using DSP in a real-ocean test the PcFF80 was easily able to see a small simulated bait fish (a single 3/4" diameter 12V car tail light bulb) at maximum red intensity at a depth of 130 feet when a standard 440 watt RMS fishfinder also using 200khz could not even detect the light bulb.

When fishing you can switch to DSP mode to use less than one tenth the power of standard fishfinders to help reduce the clicking noise which could scare fish.

In DSP mode the PcFF80 is almost immune to noise created by transducer slap so you will find that at high boat speeds the PcFF80 performance is better than standard analog-only fishfinders without the noise usually associated with high speed running.

All the features of the Windows operating system are available, such as multi-tasking. You can simultaneously run the PcFF80 fish finder and your favorite charting program or other software. Future software updates will be made available for download on the Internet.

The Linux version of the PcFF80 sonar is called SeaView and is available from BarcoSoft at
