    Great Product

    Have been using the fish hawk for a couple years. Had to replace the probe, because I lost the last one. I have the 840 system and newer probe works great.

    Bought a backup in case I lose mine. Can't fish salmon without one.

    Engineering Masterpiece

    This is an instrument, not a tool. It measures useful information very well, it is user adjustable and simple to operate. The standards of manufacture and assembly appear impeccable.
