Techno 8.5㎡ set Techno Plus Includes a 490 mast, extension, 50cm fin, and boom. This set is suitable for those who are already using Techno 7.8. Although it has been used a few times, it shows signs of aging. *Boom is an older model. Shipping costs are high, so I can't offer much of a discount. Please refer to the photos for condition.
