I have tried so many different clamps for my cameras when recording gigs. All have not been versatile enough to use on the many different fixing positions.
This one - in conjunction with a small camera extension arm fixed to it by the thread provided on the Saviour Clamp is the answer to the many fixing locations,shapes and dimensions I have encountered on the gigging circuit.
Worth considering as cheaper alternatives will soon add up to more cost once you buy, use and discard them.
