What Exactly Is a "Waterproof Camera"? The 3 Types You Need to Know
Before comparing models, it's worth clarifying something almost no guide explains: under the "waterproof camera" label, there are three very different types of cameras, and choosing the wrong type is the most expensive mistake:
- Action cameras (GoPro, DJI Osmo): small, designed for action video (surfing, kayaking, drift diving). Waterproof out of the box up to 10-18 m without a housing.
- Waterproof compact cameras (Nikon Coolpix W150): traditional sealed photo cameras with zoom and simple menus. Best for families, pools, and calm snorkeling.
- Underwater analog cameras (Nikon Nikonos): 35 mm film cameras designed for deep diving. For experienced divers, collectors, and artistic projects.
This guide covers the five best models of 2026 available refurbished in Spain, indicating for each its type, how deep it can go without a housing, and its real store price.

Buying Guide: Choose by Depth, Activity, and Budget
1. By depth: for snorkeling and pool (up to 10 m), all work. For recreational diving without a housing, the DJI Osmo Action 4 (18 m) or the Nikonos-V (50 m). To go deeper with a GoPro, you'll need its dive housing (up to 60 m, sold separately).
2. By activity: action video (surfing, kayaking) → action camera with good stabilization (HERO9, Osmo Action 4). Calm family photos → waterproof compact (W150). Contemplative or artistic diving → Nikonos-V.
3. By budget: under €200 → GoPro HERO9 Black (€149) or Hero 5 Session (€175). From €200 to €300 → Coolpix W150 or Nikonos-V. No limit → DJI Osmo Action 4 (€500). All prices are for refurbished units, inspected and with warranty.
