We currently do not offer a trade-in for users wanting to move from the RECEIVER MK3.1 to LATITUDE.
The Receiver MK3.1 is a compact and hardy 3 motor driver, and is not obsoleted by the LATITUDE range.
The LATITUDE range of products does add significant integration and capabilities when used with RED cameras, but are otherwise based on the same technology.
In most cases, we would recommend that adding a LATITUDE-MDR to a MK3.1 kit is the best option as it allows the greatest flexibility, including running in TRANSMITTER MODE (where a roaming LATITUDE-MDR attached to thumbwheels can transmit commands to a RECEIVER MK3.1 or LATITUDE on camera).
We will consider running a small trade-in discount for users wanting to switch a Receiver MK3.1 for a LATITUDE model in 2017. Email us if you want to be notified if/when this happens!
