What the thread found

• The PRO arm allows adjustment to lighter loads by removing spring canisters in about 15 seconds, making it lighter than the G70 for minimal payload work.
• The G70 arm enables tool-free on-set adjustment of lift tension through knobs, while the PRO arm requires a hex wrench for adjustments.
• The PRO arm features a lifetime warranty and non-extruded machined construction, while the G70 uses extruded construction with limited warranty information from the manufacturer.
• The G70 arm has a boom range of approximately 32 inches compared to about 28 inches for the PRO arm when measured hard-mounted.
• The G70 arm delivers smoother and more consistent iso-elastic booming throughout its range regardless of carried weight according to comparative testing.
• The G70 arm is lighter in weight and provides better weight savings on the operator when carrying heavy loads.
• The PRO arm is easier to disassemble and clean, and can be rinsed with water once spring canisters are removed.
• The PRO arm has been extensively tested with certain camera systems, while the G70 had limited field testing with that equipment at the time.
• Spring canisters on the PRO arm can be purchased in multiple sets for redundancy and simplified field maintenance.
• The PRO arm has all moving parts and bearings sealed and protected from environmental exposure.
• The G70 arm features tool-free arm post changeover and adjustable drag settings.
• Extruded arm construction as used in the G70 is adequate for intended loads when properly designed, contrary to claims that machined construction is inherently superior.

Depends on

• Comparison is from 2006, making it potentially outdated regarding both arm designs and manufacturing improvements.
• Price information varies significantly within the discussion and is affected by currency exchange rates.
• Limited field experience with the G70 was available at the time of discussion, particularly with certain camera systems.
• Warranty information about the G70 was uncertain and subject to change according to participants.
• One user's positive G70 experience was after only four weeks of use, which may be insufficient to assess long-term reliability.
• Performance comparisons are subjective and depend on individual working style and project requirements.
