After insuring you're safe and then providing for their immediate safety via the Rescue Stick, the next item in the kit is the Throw Bag. The heavy duty buoyant bag holds 50 feet of floating rope. As with all such devices, you would throw it past the victim and pull it back over them, allowing them to grab on so they can be pulled into shore, the dock, boat, whatever.
So, how well does all this work? Well, the MD3025 PFD is easy to get on and easy to inflate - assuming you're not a career chain smoker who can't fill their lungs with air. The rope bag itself DOES float and the rope also floats (individually tested in the Chesapeake Bay). As to the Rescue Stick... the literature from Mustang Survival says that the Rescue Stick is so moisture sensitive that the carry container for the kit has a Humidity Indicator and Silica Gel packs to absorb moisture. The box itself (made by Storm Case) is air and water tight and impact resistant. When I dropped the Rescue Stick into the Chesapeake Bay inflation was almost instantaneous. The horseshe shaped device was larger than I expected and I think I could have gotten two people inside the curve if necessary. Just in case the auto-inflate feature doesn't work, Mustang Survival also designed in a manual inflation device. It's (essentially) a red plastic handle on a cord that, when pulled, activates the inflation mechanism.
As "basic" kits go this is a very complete package. However, for those who don't feel they need each of these pieces, Mustang Survival also markets the MRK120 and MRK130.
The MRK120 contains four Rescue Sticks, one Throw Bag, user reference material, the Humidity Indicator and Dessicant (Silica gel).
The MRK130 is the same as the MRK120 minues the Throw Bag.
If you own a boat... if you regularly work in or near the water... if your team is responsible for equipping or maintaining boats or even jet skis... the MRK110 isn't so big that it can't be included. Less than two feet long and smaller than eight inches in height and width, the package is fairly compact. Maybe you should check them out.
