Hi all
Just in regards to finin's comments, while I agree with finin in some respects, fishfinders aren't just for finding a location. I don't think there's anything wrong with embracing technology, just as one utilises the internet to discuss fishing rather than the old methods that fishermen used, like discussing the matter down the pub.
Anyway, I got my fishfinder recently and to be honest, while it hasn't helped me catch much more fish yet, it has helped me to discovered a whole new world. For example I found a depression in the Bay that I never knew was there. I did fish the drop off around it and caught bonnies that are attracted to it. No body told me about that spot and I rarely see people fishing near it.
Old information is invaluable, such as the info finin has about marks. But info one gets from fishfinders only adds to that. Once someones finds their own marks, with the use of a fishfinder or otherwise, they soon learn how to locate it without using the fishfinder. Fishfinders just help you to find new info.
