I was just suggesting a possibility, not saying it was definitely what he was doing or endorsing it as a method. Though in this case, if that is what's happening, it looks like the device would only be moving a relatively short distance because it seems to be connected to a small webbing loop rather than a full sling.
Yes that’s what I was thinking. Though the sling is short, in the event of a fall the device would be out of reach.
Im sure Tommy knows what he’s doing as he’s done a bit of multi pitch before....
He's using a pretty standard multi-pitch belay technique if you hail from the Eastern Alps, which is a direct belay off the anchors. There are various methods but most limit the size of the sling or loop (or omit it completely) that the device is clipped into. This method is referred to in the user instructions for the device under section 11.
There's a pretty interesting video by ENSA which appear to show this method has advantages over the methods we are taught (belay off the harness) in some situations - it's a subject of some controversy though: youtube.com/watch?v=eqZQnCGl24A&
At 07:30 in that video he builds the biggest cluster of a belay. I cant get my head round what is happening. It may be optimal but there must be something said for keeping things simple!
