North Australian FISH FINDER TM forums

Im sure some will find this usefull ,google up(Demystifying depth sounders) its an article done by club marine & if anyone has other sites relating to their use that would be handy as well. For Furuno users there is ,Tuning Furuno Sounders for optimal performance, I have the Furuno 620 & theres some usefull stuff on there.

Thanks for the tip Max, I've got Furuno gear so any extra info re. Fine tuning will be good.
