  • The C400 is perfect for snorkeling, recreational diving, and pool training, with a maximum depth of 32.8 ft. For emergency rescue or as a backup for professional diving, it can be used at depths up to 98.4 ft, but only in emergency situations.

  • Always avoid standing directly above the tank while inflating. After inflation, make sure to relieve the pressure to prevent any hazards.

  • Inspect it annually to ensure it's functioning properly. After each use, rinse it with fresh water and store it in a dry place, away from direct sunlight.

  • For home use, the electric air compressor is ideal. You can also quickly fill the tank by connecting it to car's engine. The scuba adapter allows for fast on-site refills, and the tank meets DOT standards for convenient filling at local dive shops.

  • A full charge provides 15 to 20 minutes of use, depending on individual lung capacity and dive depth. Be mindful of the pressure gauge during your dive, as usage time can vary.

I had a leak in my pool I could not find I wasn’t able to hold my breath long enough to find the hole so I ordered this in 10 minutes later I found the hole in the deep end. It works very good. I wish the air supply was a little bit longer. I could only get about 10 minutes out of it And definitely by the electric pump because even with the electric pump it takes 20 minutes to refill doing it by hand, you’d be there forever.

Great deal, high quality gear. Just wish it was a 1.5L instead.

My friend got the regular tank, but this kit with the refill adapter is SO much better. We were on a recent diving trip, and his tank ran out way before mine! Having the adapter saved the day - we were able to refill right on the boat and keep exploring.

Initially, I was hesitant about the extra cost for the refill kit. However, after using it, I can confidently say it's worth the investment. The ability to refill my tank on the go provides so much more flexibility, especially on multi-dive days.

Also I need 6 pounds of weight to go underwater. If I had a choice I would go with the 2 liters next time.

The refill adapter is such a time-saver! I can top off the tank between dives without having to head back to shore. The whole setup was easy to figure out, and it’s been super reliable.

This tank is super compact and light, making it great for spontaneous diving trips. I can just toss it in the car and hit the water. The storage bag is well-designed and keeps everything snug. It’s really easy to carry around, and it makes short dives so much more enjoyable without the hassle of lugging heavy gear. Great for anyone who loves some on-the-go underwater exploration!
