Mini Scuba Diving Tank with Sub-Mask

el producto me parece bueno lo malo es la bomba para llenar el tanque de oxígeno

Funciona muy bien, pero es trabajoso cargarlo con la bomba devmano

great cuality .

Directions suck, tank does not fill up at all, the directions are of a product that I was not sent. Pump is different Likely a gimmick, would love a working product that was in the directions

I was really excited to use this but unfortunately the pump isn't working. I was trying for a good 2 minutes none stop but the gage wouldn't move, the pump even got hot. It will double as a snorkeling mask for now until I try to figure out what's wrong

When I first received the unit, even hundreds of full strokes on the pump wouldn't show any increase in pressure. When I checked the fittings on the tank and pump, I found all of them loose. Also, you need to "oil" the pump shaft (look carefully at the pump instructions). After tightening all the fittings and oiling the pump shaft, it took the expected 500 pumps to bring the tank up to full pressure. I have a large lung capacity, so the tank only lasted about 5 minutes and the last 100 strokes of the pump were far more difficult than the first 400...so I bought an electric pump that makes life easier. The mask seals well and the double-snorkle feature is nice when not using the tank.

My daughter loves it. Even just to goof around in the pool with. The hand pump though....be prepared to pump this thing for and hour. Going to look at getting an electric pump for it.

Overall, I've been very pleased with this set. The tank is only good for a handful of minutes - between 6-8 minutes is what you should count on. It works well in tandem with the snorkel mask and standalone with the regulator. I haven't had any issues with the mask fogging. It isn't overly large so it is easy to use without being heavy or inconvenient. This is great for short dives, in my case, for shells and/or fossils. It could also easily be used as an emergency/back up tank. The pump it comes with it is not efficient. Even being a small tank, it is just not effective or realistic to try and fill a tank in this way. I can fill this little tank within thirty minutes with my compressor. Overall, I'm happy with this set.

Don't buy this product if u want to use it under water. To refill the tank will take u about 500 pumps to get full. The instructions are not the best. Took me about 2 hours to figure it out. Took me another 45mins to get enough air into the tank to give me less than 5 mins under water. Waste of money for want I wanted.
