−$80 vs. fair-price low

Fair-price range: $400–$650

A like-new ScubaPro MK25 with S600 and upgrades listed for just $320 on Facebook Marketplace.

Why we flagged this

Watch out

The seller explicitly states that the buyer is responsible for having the equipment verified and serviced before use; there is no provided receipt for a recent service or hydrostatic test.

Santi Elite Plus Drysuit

Like new Santi Elite Plus drysuit for A$3,000 (~$1,950 USD) in Sydney—half of retail price with extensive accessories.

Why it's a deal: The asking price of A$3,000 (~$1,950 USD) is approximately 50% of the retail value (~$5.5k-6k) mentioned by the seller. The 'like new' state and the inclusion of $200+ in additional accessories (Bioneck seal, hanger, etc.) make this a significant below-market opportunity.

Watch out: Verify the specific sizing (Height 174–178 cm / Chest 112–116 cm) as drysuits are non-adjustable. Inspect the latex neck seal for any degradation or tears. Because this is a Facebook Marketplace transaction in Sydney, ensure a secure payment method or in-person inspection at the provided St Leonards location.
