What has been the biggest change in fishing

[Anglinarcher]

Note sure that those are all that new, just perhaps new to you.  Tungsten jigs have been around for a long time; people just started to spread the hype.  Fluorocarbon line has also been around far longer then 5 years.  It still is too stiff, too much memory, too expensive, but the hype is catching on.

My first underwater camera is at least 15 years old.  It may have been better and far less expensive then what we get now.

Fish finder tech?  Well, you have me on that one.  They are getting crazy good now.
