Off on holiday soon which will involve some snorkelling and someone suggested getting a go pro to film the pretty fishies I might then use it on the bike when I get back However, it's a very confusing product range. I don't need to spend a fortune, don't need super duper quality but I'd like something that's going to work as needed. I realise that they don't have the best battery life but I don't think that'll matter too much Needs to be simple to use for a non gadget person (me)! The Hero 7 looks like a good option. It's not 4K whatever that might mean in reality. I don't have a 4K telly so presumably I don't need it in my life! https://www.johnlewis.com/gopro-hero7-white-camcorder-1440p-full-hd-10mp-wi-fi-waterproof/p3745760 Any other suggestions gratefully received. I'd rather buy new with warranty even if it costs an extra £50 (JL give 2 years and accidental damage for £20) While I'm at it, can anyone suggest an inexpensive but decent snorkel and mask combo!
