The primary use is logging radio transmissions while walking. I have my hands full already and when I tried using my phone found it awkward and very inconvenient to manipulate. Already holding a notebook, pen and sometimes a GPS (although this is on a lanyard).

Mark R: I like the pad made from an insole. I have tried various materials for that application in the past and found most caused some sort of problem. Mostly sweat which attracts dirt which then irritates my wrist from abrasion. Leathers adsorb the sweat which turns the pad into a nasty biological community that I would rather not have strapped to my wrist. Besides leather does not last long in the tropics.

However the insole material may be immune to these problems. After all I can't think of a worse environment than inside a shoe. Well worth a try. Thanks.
