Description
Overview
The Insta360 GO 3S is Insta360’s latest and most powerful thumb-sized camera, building on the beloved GO 3 with significant upgrades. It shoots 4K video at 30fps — double the pixels of GO 3’s 2.7K — all from a camera that weighs just 39.1g, about the weight of a lightbulb .
Key upgrades include a 50% more powerful processor, 10m (33ft) waterproofing (up from 5m), Apple Find My compatibility, Dolby Vision-ready HDR, and 1080p slow motion up to 200fps . The camera uses the Action Pod (96.3g) with a 2.2-inch flip touchscreen for remote control, preview, and charging.
This unit is in 99% like new condition – barely used, virtually flawless, fully tested. 10 months of remaining manufacturer warranty provides exceptional buyer confidence — nearly a full year of coverage. Includes Action Mount Set, silicone case, carry bag, and 3-prong adapter.

Why This Camera
4K Video – The Main Upgrade
The GO 3S captures 4K at 30fps — nearly double the pixels of GO 3’s 2.7K. Sharper details, clearer footage, and more flexibility for cropping and stabilization .
10m Waterproof
The GO 3S camera is waterproof to 10 meters (33ft) without a case — double the depth of GO 3’s 5m rating. Beach vacations, pool days, and rainy trails are no match . The Action Pod remains IPX4 splashproof only when the camera is installed.
Apple Find My Compatible
Misplaced your tiny camera? If you’re an iOS user, you can easily track it down using the Apple Find My network — a crucial feature for a 39g camera that can easily slip out of a pocket .
10-Month Remaining Manufacturer Warranty
This unit includes active manufacturer warranty coverage for 10 more months. This covers defects in materials and workmanship — a level of protection no other used listing at this price point offers.
Action Mount Set Included
The Action Mount Set includes multiple mounting options for hands-free POV shooting. Mount the camera to helmets, straps, backpacks, or gear for unique perspectives.
3-Prong Adapter Included
The included 3-prong adapter makes the GO 3S compatible with standard action camera mounts (GoPro-style), dramatically expanding mounting options for creative shooting.
FlowState Stabilization & Horizon Lock
The GO 3S inherits the excellent FlowState stabilization from previous models. Horizon Lock keeps footage level even when the camera rotates — essential for action sports and dynamic shots.
Honest Note
The GO 3S launched in June 2024 and remains Insta360’s current tiny camera in 2026. What you get: 4K video in a 39g body, 10m waterproofing without case, Apple Find My integration, and a valuable accessory bundle. What to consider: The Action Pod is not fully waterproof (IPX4 only), internal storage is fixed at 128GB (cannot add SD cards), and the camera’s small size makes it easy to lose (use the Find My feature).
This 99% unit is virtually flawless — minimal to no cosmetic wear, fully functional, ready to shoot. The 10-month manufacturer warranty makes this as worry-free as buying new.

POV creators wanting true hands-free 4K capture
Pet owners filming from dog or cat perspective
Travel vloggers who need an ultra-discreet camera with warranty protection
iOS users who value Apple Find My integration
