Here’s a breakdown of the Odyssey Square 2 Square TRI‑HOT #7 Putter (aka #7 model) — what it offers, what to check, and an estimate of used value in South Africa.

Key Features & What It Offers

• The TRI-HOT Square 2 Square line by Odyssey is a “zero-torque” style putter design, meaning the shaft enters near the centre of gravity (CG) of the head to reduce twisting at impact. The #7 model generally offers a “fang” shape (two prongs) with a mallet footprint, large alignment features and higher MOI.
  

• Features include: Ai-DUAL insert (dual layer urethane) for consistent ball speed and improved forward roll; new multi-material construction; revised hosel/shaft position for more “traditional” look at address.
