I don't think it's fair to dismiss people as noddys for using technology tbh, some will be but some will be experienced anglers who can use it to an advantage,
Most of the anglers who make a career at it have used bait boats, echo sounders etc at some point, it's just a tool some people will use and some won't tbh, it's not up to me to decide who is doing it right or wrong as long as I am OK with what I do myself and I enjoy it, and as long as the noddys don't keep casting into my swim or telling me where I can fish I will be fine 😁😁😁😁😂
I think there is probably too much emphasis these days on needing all the top tackle to become a carp Fisherman and also the scene has definately changed since I was younger, I daresay newer anglers are influenced into thinking they need a deeper to compete and really expensive kit and that will catch them more carp,
Sadly it seems too many people and kids are missing out on an apprenticeship and fishing straight away for carp, i find that a bit saddening but unfortunately all the small village pond type venues seem to be dissapearing and people are learning what they see on you tube, which isn't a bad thing as knowledge has never been more available but they are being influenced into needing these things as the content providers also need to pay the bills
