Best speed and temp probe on the market, I have used many others but this is constant and never loses signal nor temp.
Very Clever piece of equipment,which not only helps you catch fish, but adds to the enjoyment of fishing,
wont leave the dock with out it.
My favourite Fishhawk product. Has made my understanding of fish and their whereabouts that more interesting.Has added an extra layer of enjoyment to my fishing.
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.
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.
