Marco Polo - Tracker Set
From Tim Crabtree at Eureka Products regarding possible interference:, Regarding interoperability with your existing control and video telemetry systems, our tag transceiver (the part the goes in the model) does not transmit any RF energy until commanded to by the handheld locator. In fact, each and every transmission it makes is only in response to receiving a command from the locator. The user is in total control of that from the ground so interference during flight is not an issue., Includes:,
Quickly and easily track, locate and recover wayward RC models with the Marco Polo RC Model Recovery System. Simply attach the compact and lightweight tag transceiver to your RC Model, turn it on, and you're ready to fly!
The primary consideration for interference is other onboard radio
s, that may still be active after a crash, desensitizing our tag transceiver. Certainly, if we are trying to receive a distant locator transmission arriving at -125dBm and an on-board radio is sending video data at +30dBm in the 900Mhz band then there is going to be an issue. 2.4GHz and 5.8GHz are definitely not a problem. 433MHz might be a problem from the second harmonic although typically the odd harmonics are more prominent. Not sure about the lower frequency transmitters, I doubt there would be a problem, by the time you get to the 10th harmonic I think the energy would be so low that jamming would not be an issue. We use 50 frequency FHSS so a single channel interferer is also not an issue. Of course, the best protection against interference is to shut down all other onboard transmitters when possible or just wait for the batteries to die.
Should you lose control of your RC Model, just put your Marco Polo hand-held locator into track mode. The locator will immediately search for the tag transceiver, and when it acquires the signal give you real-time direction and distance to your model. Just walk, following the arrow and Marco Polo will lead you right to your model, within inches if necessary. If the tag transceiver is initially out of range you can walk or drive around until you come within range and the locator will then guide you directly to the location of your model.
Simple to setup and use, single button-push to begin searching for lost RC model with real-time distance and direction feedback
Works anywhere, totally self-contained, no GPS or cell network required, no monthly service contracts, ideal for remote areas
Rechargeable lithium-ion battery transceiver tag gives you up to 10 days to find your lost model
Super small, compact tag transceiver easily fits on even small RC models, weighs only .42 oz. (12 g)
Does not interfere with RC radios – Marco Polo only transmits when you activate search mode from the handheld locator
Great solution for recovering model rockets as well
Each Marco Polo system supports up to three tag transceivers (system can track one transceiver tag at a time).
It has been proven to track airborne craft, 433mHz control and 1.3 GHz video out to around 2.5 miles.
Furthermore, in house testing here at ReadyMadeRC, LLC concludes that we were able to successfully locate a downed 400 size quad about 1/8th of a mile away in knee high grass. The entire process took under 14 minutes, from the time the tracker was started till we were flying the quad back to the launch point.
