Porth is usually only diveable in the height of summer (but we didn't have one last year) or the depths of winter. It is almost April, but it looks like we are still in the latter. Which is good, as it is freezing overnight and keeping the water levels down.
We took a quick look at Tradesmans entrance (Divers main entrance) and the water was clear although not at it's lowest..it is diveable.

I have treated myself to some new graphite pencils which are lovely to work with underwater. Rich has treated us to a new sonar underwater device which will speed up surveying immensley and we'll no longer need to use the painstaking method of builders tape measure. The line is well tagged and laid but for absolute maximum accuracy as well as passage dimensions, the route from Tradesmans entrance right through to Top entrance (a traverse) has been surveyed with tape measure by myself and Malcolm Stewart.
