I have just seen an advert about Preston Innovations new heated seat box cover to fit any seat box with a portable power pack. I think it would sell well for beach fishing.
I stopped doing it because . I had done it several times and didnt want to be repetitive, however, now you ask , quite a few of the over 50s use Yuki Kenta TRT rods. These are between £600 and £700 each. Very expensive but you do get what you pay for. . Ill remember to ask on my next video.
