Upgrade RB4 TX from Standard to Long Range
We can upgrade your Standard RailBoss 4 Transmitter if it uses AAAA batteries. The older version with the CR2032 coin cell batteries cannot. The standard TX can also be identified by the label on the back. It will have an SM200 on it. The long range will have SM220. Ideal line of sight range for the long range is 800 feet, as opposed to 400 feet for the standard.
Note: As of 8/25/2018, all transmitters shipped are Long Range. (A decision based on economics, not performance)
