Field Marshall 1000 Receiver-Intended Use

This receiver doesn't rely on crystals to determine the frequencies it can cover. An all-digital circuit allows the same receiver to pick up any frequency in the 216 through 219 MHz bands. It comes in three different models, 100 channels, 1000 channels, and 4000 channels, allowing every frequency you could possibly want or just the ones you're interested in, for less money. Best of all, if you change you mind down the road, your same receiver can easily be converted to a different set of frequencies.

Electronics are housed in a robust case machined from a solid block of aircraft aluminum. Purposely made for heavy outdoor use, this tracking receiver is designed to give you more years of trouble free operation through the widest range of temperature and weather than any other.

Greater portability and reduced size is achieved without the handle on a third axis. But having a center-balanced handle on a tracking receiver is a definite advantage for longer walks or when holding it out the window of a moving vehicle. So, how to have it both ways? Answer: The Quick-release handle. Now, you can choose when to use it and when to put it away in another pocket.

We kept the same, field proven, collapsible, three-element directional antenna design for maximum directionality. It’s a full gain yagi when deployed, but now it collapses to an even smaller size. We reduced the size of the brackets, the sliding booms and eliminated the need for cables, cable savers and big springs found on the previous design. Also rugged solid rods are now used for the elements instead of hollow tubes.

Three red LEDs now illuminate the control panel for better clarity in the dark without compromising your night vision.

The slimmed down design fits even better in your hand with the handle removed. Designing the case to also be hand-held required we make other important changes, like a larger radius on all corners, and counter-sinking the earphone and power jacks to make them flush with the surface of the case, which just makes it feels more like an over-sized iPod in your hand. Dave the receiver board was redesigned and shrunk to about 20% less area, with everything fitting inside much more tightly. We then asked our design team to "vacuum pack" the case down to the absolute minimum required, with no wasted airspace on the inside. Turns out the case is much more stout and rugged than even the previous box.

Handle attaches to the receiver, or directly to the antenna. So, now you can have it your way: use together in one single piece, use without the handle, or wear the box safely around your neck and connect the handle directly to the antenna to hold outside the window in the rain.

Hold the receiver down waist high and you have two speakers facing up at you. Hold it up high for better reception and you still have a speaker facing down at you. By incorporating three speakers, the sound on the 2007 Field Marshall has been increased in volume. More importantly, it has improved the sound’s omni-directionality which means the volume doesn't change as you rotate the receiver, a definite problem in other receivers that leads to erroneous perception of the signal strength in certain directions.

Nearby transmitters on other channels sometimes cause interference to your reception, but this receiver has special circuits to minimize the effect.

The three range settings (Far, Medium and Near) have been adjusted so that each of them covers a much greater range than before. You can therefore switch between these in most situations to get an idea of how far from you the bird or dog really is.

With the new digital receiver board inside the Field Marshall, we’ve improved sensitivity by another 3dB, to equal that of the Marshall Stealth Receiver, the best on the market. This means a significant increase in reception distance for the same transmitter.

Improved shielding means you can track up to within inches of a transmitter lost in the grass with the same pin-point directionality you get at a distance. The full-size three element yagi gives the best range and directionality of any antenna, and reduces the "back lobe" which sometimes fools people into tracking 180 degrees backward, in the wrong direction.

A broadened, smoothed tuning mechanism means that tuning into the signal is a pleasure and much faster than before. The tune knob is not "touchy" and is also protected from accidental contact by a cowling so it’s not easily bumped off your tune setting when getting in and out of the vehicle.

The actual sound of the receiver has been improved through the elimination of harsh harmonics and distortion, making it easier to track weak signals and far more pleasant to listen to.

A new narrow-band filtering system is employed rejects noise better without reducing your signal, so you hear the signal more clearly with less distracting background noise, even for the weakest signals.
