Frequently Asked Questions About Sealion Diving

DOES SEALION FLOAT?

Yes, the SeaLion is designed to float on the surface of the water.

WILL A SEALION FLIP OVER?

The Brownie’s THIRD LUNG™ rides well on waves and is even built to take a splash. If conditions are suitable for safe recreational diving, the Brownie’s THIRD LUNG™ will handle the waves. Breaking waves near shore, however, are a different concern. A breaking wave in the surf zone or a large wake from a boat could potentially flip the unit, so the user must seek safe operating areas as part of their pre-dive checklist.

If you are diving from shore, a hands-on transfer through the surf is essential. If you are diving from a boat, take special care in placing the Brownie over the boat’s transom and into the water. Lowering the unit straight into the water ensures a safe launch.

IS SEALION AIRPLANE FRIENDLY?

The SeaLion dive system itself is designed for portability and can be transported relatively easily. However, due to TSA and airline regulations, the SeaLion's lithium battery is not permitted on airplanes because of its size and capacity. When traveling by air, you would need to make arrangements to have the battery shipped separately.

IS IT HARD TO PULL A SEALION ALONG THE SURFACE WHILE DIVING?

You might be surprised, but there is less water resistance in towing a THIRD LUNG™ than in swimming with a full set of SCUBA gear. Considering that most Brownie dives are shared between two or three people, swimming with a THIRD LUNG™ is very easy. Conditions can increase the drag; windy days may make towing more noticeable. Many people simply drift dive on days when the wind is a bit strong, allowing the surface unit to gently tow them along through a dive.
