I think it's a bit of a shame that there needs to be convoluted explanations or reading between the lines about fixed aids (navigational marker / bat roost etc.). More so when it actually affects what gear you bring with you.
Aquamole for example. A group from our club were planning to go the other day and came to get some gear from the shed. (They never actually went down and went to Yordas instead because someone forgot their jammers, but that's another story....) If you follow the CNCC route description & topo, it suggests a rope-protector is useful for the entrance pitch. No mention of the convenient scaffold bar, where taking a sling to re-belay off the bar would be nice. Avoiding the rope protector issue entirely.
Looking at the entrance photo on the CNCC aquamole page, it shows a closed lid and no bar. If you look at the photo in this thread (https://ukcaving.com/board/index.php?threads/aquamole-pot-entrance.13617/
) it's nice and obvious there's been a bar for 10 years. Maybe they could put that photo on the CNCC page, so even if people aren't comfortable adding the actual bar to the description & topo they could see it on the photo. I haven't got NC3 to hand, maybe it's described in there anyway.
It seems odd that this bar isn't included, but the 100+ scaffold tubes in Notts 2 are described as anengineering masterpiece climbable descent route with a confident "No Tackle Required", "Consider belay rope"
Please don't take this as criticism, the CNCC topos and route descriptions are superb. Particularly in NC1 & 2 areas where the guides are out of print. It just takes a bit of interpretation sometimes. Maybe that's for the best and you soon get used to it with experience.
It all just seems a lot of work and words for "Caving is potentially dangerous, use your judgement."
No one bats an eyelid when the BMC publishes a climbing guidebook that says "Superb route, 3 stars, bold, protected by a single poor peg."
