Dave the Diver Map Guide
Every biome — fish spawns, resources, bosses & secrets

The Blue Hole is bigger than it looks. 7 distinct biomes spread across 650 meters of depth, each with unique fish, rare resources, and boss encounters. This guide maps every zone — what to catch, what to avoid, and what to upgrade before venturing deeper.

Your starting zone. Perfect for stocking up on basic fish and seaweed. The Titan Triggerfish is the only real danger — approach from behind to avoid its charge.

Blue Hole Depths

This is where the money starts. Red Crab and Tuna are your early profit engines. Watch for Moray Eels hiding in cave walls — they telegraph their lunge with a head-bob.
