RX-SPECIAL Telemetry Receiver

$ 1,100.00 USD

The RX-SPECIAL synthesized receiver covers any continuous 4MHz frequency spread between 148.000 MHz and 174.000 MHz. The system includes a folding Yagi antenna which mounts directly to the receiver. The receiver is nicely balanced on the antenna for comfortable, one handed operation.

The RX-SPECIAL is extremely sensitive to hear the weakest telemetry signals, it also employs very effective filters to eliminate unwanted interference sources. The synthesized design provides excellent temperature stability with no drift in frequency settings. A four step attenuator allows full receiver sensitivity for longest range or reduced sensitivity for extremely close-in tracking to a few inches. It employs a large, full range, speaker for rich sounding loud audio. A very sensitive signal strength meter also doubles to let you know when the battery needs replacing. A rugged, light weight, aluminum case is standard as well as a 3.5 mm mono headphone jack. A standard circ., 5.5mm x 2.1mm, center positive, power jack allows the RX-SPECIAL to be powered from an external 9-14VDC source. Select range of 4.000 MHz from  148.000 MHz to 174.000 MHz.

Sawyer MINI Water Filtration System

$ 45.00 USD

The lightest and most versatile personal water filtration system, the Sawyer MINI weighs just 2 ounces, fits in the palm of your hand and provides 0.1 micron absolute filtration, eliminating 99.99999% of all bacteria, such as salmonella, cholera and E. coli, eliminating 99.9999% of all protozoa (such as giardia and cryptosporidium), and eliminating 100% of microplastics.

Attach the easy-to-use MINI to the included drinking pouch, use the included straw to drink directly from a water source, connect to hydration pack tubing, or screw onto bottles standard disposable water and soft drinks.

Rating up to 100,000 gallons of filtered water, the award-winning MINI is perfect for everything from camping with the kids to traveling abroad where water can't be trusted tap and bottle to equip your emergency bag.

How does it work?

 

 

Absolute filtration of 0.1 microns.

Water filters contain a large number of small 'U' shaped hollow fiber microtubes that trap contaminants while allowing decontaminated water to pass freely at a high flow rate, removing the need to store water and reducing the possibility of contamination of the water after the filtration process

The Sawyer MINI is certified for 0.1 micron filtration, which means there is no larger than 0.1 micron pore size. This makes it impossible for harmful bacteria (such as salmonella or leptospirosis), protozoa, or cysts such as E. coli, Giardia, Vibrio cholerae, and Salmonella typhi to pass through the filter.

All Sawyer water filters meet or exceed the removal rates recommended by the Environmental Protection Agency (EPA).

Maximum versatility.

Ideal for outdoor recreation, hiking, camping, exploring, domestic and international travel, and emergency preparedness, the Sawyer MINI gives you multiple ways to access clean water.< /p>

Simply fill the included reusable bag with any water source, screw the filter onto the bag and drink directly from the filter or squeeze the water into a water bottle.

You can also drink directly from water sources with the included straw. For even more versatility, screw the filter onto most standard disposable water or soda bottles, or attach it in-line on hydration packs (sold separately).

100,000 Gallons.

Rated to filter up to 100,000 gallons, the MINI's filtration membranes are tough enough to withstand backwashing with the included syringe, restoring up to 98.5% of the filter's flow rate. filter.

The MINI can be cleaned and reused almost indefinitely without having to replace expensive cartridges... ever. We recommend washing and disinfecting the filter after each outing for optimized use.

Top Filtration.

In addition to the added versatility of being able to fit any standard 28mm threaded bottle or bag, the Sawyer MINI filter provides higher levels of water filtration and lasts longer than other filters personals on the market.

All filters are air tested three times before leaving our production facility to ensure that no pathogens can slip through the fibers of our filter, a statement that no other water filtration company can do.

With a total field weight of just 56g, the MINI compactly rolls up into its included collapsible mylar bag to take up minimal space in your pack and won't weigh you down.
