Garmin inReach 3 Dive Case
Garmin inReach 3 Dive Case — Product description
The Garmin inReach 3 Dive Case lets you take your inReach Mini 3 down with you. It's water-resistant to 100 meters (10 ATM), so your satellite communicator rides safely on the dive and it's ready to send an SOS or check in the moment you surface. Simple, sealed protection for divers who don't want to leave their inReach topside.
If you dive with a Garmin inReach Mini 3, this is the case that lets you bring it along without babysitting it. The inReach 3 Dive Case is a water-resistant housing built for the Mini 3, sealing the communicator against pressure equivalent to a depth of 10 ATM, or 100 meters. You clip it to your rig, drop in, and know your satellite communicator is protected the whole way down and back up.
Here's the honest part first, because it matters for safety. GPS tracking and satellite communication don't work underwater. Water blocks the signal, full stop. So this case isn't turning your inReach into an underwater messenger. What it does is protect the device while you're submerged so it's dry, sealed, and ready the second you break the surface. For a lot of divers, that's the whole point. You come up after a drift dive, maybe a few hundred yards from where the boat expects you, and you've still got a working inReach to check in, share your position, or trigger an SOS if the day has gone sideways.
That surface-comms scenario is where we see people reach for this case most. Drift divers who don't know exactly where they'll surface. Spearfishers working a reef off a small center console. Solo or buddy dives launched from a kayak where the boat is a long swim away. In all of those, the inReach stays on your person the entire time, protected below and live above. No stashing it in a dry bag back on the boat where it can't help you when you actually need it.
The case is sized for the inReach Mini 3, and it also fits the Mini 3 Plus. The device seats inside, the case seals, and you're set for the dive. One thing worth knowing up front: the device doesn't float. If it comes loose, it sinks. So tether it. Most divers clip the case to a BCD D-ring or lash it to a PFD strap rather than trusting a pocket. It's a touch too thick for easy pocket carry anyway, and you really don't want it working its way out at 60 feet.
Care is straightforward, but don't skip it. After any salt dive, rinse the case in fresh water and let it dry before you stow it. Salt is what wears out sealed housings over time, and a 30-second rinse goes a long way. If your case has a pressure relief valve, crack it open once you're back topside so the housing can equalize and you don't trap humid air that fogs up inside on a hot day. Little habits, long life.
A few things this case is not. It's not a dive computer, and it won't give you depth or no-deco info, so it doesn't replace your primary dive gear. It isn't rated for technical or saturation depths past that 100-meter number. And it's not a substitute for proper dive planning and a surface marker. Think of it as the piece that keeps your emergency and check-in lifeline dry and ready, not as a gadget that does the diving for you.
For the boater who already runs an inReach Mini 3 topside for tracking and messaging, adding this case means the same device pulls double duty. It rides on the console or in your pack during the run out, and it's on your body during the dive. One communicator, one subscription, protected across the whole trip. That's a clean setup for anyone who splits time between running the boat and getting in the water.
Bottom line: if you own an inReach Mini 3 and you dive, the inReach 3 Dive Case is the accessory that makes carrying it in the water a non-issue. Sealed to 100 meters, sized for the Mini 3 and Mini 3 Plus, and simple enough that there's nothing to learn. Rinse it, tether it, and it'll ride along dive after dive.

Frequently asked questions
Will my inReach Mini 3 send messages underwater in this case?
No. GPS and satellite signals don't pass through water, so no communicator works while submerged. The case protects the device on the dive so it's dry and ready to message, share your position, or trigger an SOS the moment you're back at the surface.
How deep is the inReach 3 Dive Case rated?
It withstands pressure equivalent to a depth of 10 ATM, or 100 meters. That covers recreational scuba and free diving well within that limit.
Which inReach devices fit this case?
It's built for the inReach Mini 3, and it also fits the inReach Mini 3 Plus. It's sized specifically for those units, so the Mini seats securely.
Does the case float if I drop it?
No, the device doesn't float, so if it comes loose it sinks. Tether the case to a BCD D-ring or a PFD strap before you get in the water.
Can I still use the inReach at the surface with the case on?
Yes, that's the whole idea. GPS and satellite comms work at the surface, so once you come up you can check in, share your location, or send an SOS with the device still protected in the case.
How should I care for the case after a salt-water dive?
Rinse it in fresh water and let it dry before you stow it. If it has a pressure relief valve, open it once you're topside so humid air doesn't get trapped and fog up the inside on a hot day.
Does this replace a dive computer?
No. It's a protective case for your inReach communicator, not a dive instrument. It won't show depth or no-deco time, so keep running your normal dive gear.
Is the inReach Mini 3 waterproof enough for diving without the case?
The Mini 3 handles rain and splashes on its own, but it isn't built for the pressure of a dive. This case is what protects it down to 100 meters.
Why carry an inReach on a dive at all?
For surfacing away from the boat. Drift dives, spearfishing off a small boat, or kayak dives can put you a long way from your ride. A protected inReach means you can call in or trigger an SOS the instant you're back up top.
Can I use this case for both scuba and free diving?
Yes, within its 100-meter pressure rating. Whether you're on a tank or free diving a reef, the case keeps the inReach sealed down to that depth.
