Offset Tapes:

• Measured distances are limited to the length of the tape, usually 2 or 5 metres.
• Clear paths of travel, unimpeded by physical obstacles, are needed between the end points of the distance.
• The sliding tip of the offset tape should be in good condition to maintain good accuracy.

Stylon Tapes:

• Measured distances are limited to the length of the tape, usually 30 or 50 metres.
• Clear paths of travel, unimpeded by physical obstacles, are needed between the end points of the distance.
• Large undulations in ground level can make chaining difficult.
• Distance accuracy is dependent on correct field procedures and often the application of corrections for various factors.

Chains:

• Measured distances are limited to the length of the chain, usually 50 or 100 metres.
• Clear paths of travel, unimpeded by physical obstacles, are needed between the end points of the distance.
• Large undulations in ground level can make chaining difficult.
• Distance accuracy is dependent on correct field procedures and often the application of corrections for various factors.
