I've owned a Spare Air scuba
tank for about a year now. I use it quite regularly, and I now consider it a necessary component of my cruising inventory.
If you don't know what I'm talking about, its a mini scuba
tank attached to the bottom of a regulator
. (one piece unit) Mine holds about 85 breaths working at less than 15 feet, or, about 3 minutes worth.
The darn thing has come in handy quite a few times. I'm open water
scuba certified, which you should be, to use this device.
Getting a little older, I can't do the 'Tarzan' dive on the anchor
while holding my breath anymore. I attach the spare air around my neck with a webb-strap, just to keep it from floating off. Otherwise its quite comfortable holding it with just my mouth and teeth.
I've used it to dive the anchor
to check the set, and also to dive the anchor to trip it when necessary. (I don't always use a trip line)
It's handy for grabbing that quick lobster, clearing a plastic bag from a thru hull
fitting, cutting loose crab traps, replacing zincs, knocking off a barnacle or two from the prop, picking up enough scallops for dinner... just about anything you need a short stay underwater for.
I don't have to mess with my full scuba gear
, and I'm not restricted by the length of my hooka hose. I do put two 2 pound soft weights in my pockets to keep me from floating so much.
The unit easily refills from my onboard scuba tank.
What a little gem. I highly recommend it onboard.
Fairwinds to all!
