My partner and I started using little walkie talkies (Dick Smith, cheap as, have lasted for years) for multi-pitch climbs and/or windy day climbing. Saves so much hassle, and very easy on the vocal cords. Also provides opportunities for mid-climb abusive language towards belayer/climber without shouting. Need to remember to remove the batteries when storing the walkie talkies (otherwise the power drains), but other than that, very hassle-free. |
