In reply to eric_in_cheddar:
I got a pair of cheap yellow Motorola Talkabout T72 ones earlier this year and they've been great for longer sea cliff stuff. They don't subtract from the adventure but they cut out a certain amount of uncertainty, subsequent faff, and so speed things up. Rechargeable, multi-channel and good battery life.
I find tugging ropes hard to distinguish from simply moving/pulling when anchor building (and it can lift gear on a traverse).
Downsides of the Motorolas:
- Attached by a tiny cord with flimsy carabiner plus clip. Carabiner broke quite quickly but easy to rig up better attachment using a swaged wire or cable tie and prussic loop.
- Voice activation has a lag, it activates part way through a sentence but seemingly through any kind of gear clank on the harness. Much better to leave it in "press button to talk" mode.
