SM-3 SOLAS Lifebuoy Marker Light 

The SM-3 is a high intensity LED strobe which provides 360° visibility for approximately 2 miles.  This compact yet durable marker light facilitates rescue by automatically activating and beginning to strobe when in the water, working for over 40 hours at 30°C (86°F) or over 24 hours at -1°C (30°F).  Perfect for commercial marine, petro-marine, cruisers, and any other application needing a reliable Crew Overboard Marker (COB) light, the SM-3 floats upright in all conditions, ensuring it will keep shining when you need it the most.

With a minimum light intensity of 3 candelas throughout its entire operating life, this high intensity LED strobe clearly marks a crew-overboard site with each brilliant flash.  It automatically rights itself and activates when in the water, ensuring that activation is never an issue that a crew member in distress needs to worry about.  The SM-3 operates on 2 AA Lithium batteries and the batteries are user replaceable, allowing the potential for a longer product life than the many disposable lifebuoy lights on the market. 

The supplied mounting bracket holds the SM-3 secure in the roughest of conditions but it is still readily accessible when needed in an emergency. 

The SM-3 is USCG/MED/SOLAS approved for use around the world and this durable LED marker light therefore provides an excellent option for vessels needing to meet USCG and SOLAS carriage requirements for lifebuoy self igniting lights. 

With its easily replaceable Lithium AA battery power source, the SM-3 will give years of service and be ready when called upon.

Nice BIG enameled cast iron dutch oven. like LeCreuset but costs less
Color: Blue, Size: 6-Quart
This is nice quality, similar to the far more costly French LeCreuset brand. I was surprised how big this model is, possibly too big for my small kitchen and limited storage space. I store it in the oven. It would be great for baking sourdough boule bread.

Enamel finish
Color: Matte Navy, Size: 6-Quart
This is an amazing pot, got the 6 Qt for beautiful roast dinners and for baking bread. All comes out evenly baked. Cast Iron is best and it has a nice finish for easy clean up.

Great quality. Easy to clean. Nice appearance.
Color: Red, Size: 4.3-Quart
Solid, heavy pot for cooking and baking. I bought it mainly for making soups, stews and breads. I have only tried soups thus far. The pot cleaned up very easily. The bottom of the pot heated uniformly. Nothing was stuck to the pot when I was simmering on the glass top stove. I have not had the chance to bake yet, but seeing how evenly it held heat while cooking, I am thinking this will be perfect. I bought the red color. It gives a nice pop of color in my kitchen. This pot will probably last me a long time. I would buy one if I needed a replacement, or a gift for someone.

Great quality for price after 3 years of use
Color: Matte Navy, Size: 6-Quart, Color: Matte Navy, Size: 6-Quart
I’m 3.5 years in and use it weekly. So far it’s been a great product especially for the price. We are really into soups, roast, and I bake bread a lot. This thing is amazing and a great quality. It’s easy to clean, does great in the oven, and stands up great to constant use. I only have a small amount of staining at the bottom, and a couple scratches from metal utensils. The lid is solid and the handle is really secure still, which is a problem I’ve had with other brands I’ve tried.
