1. One Red/Green TEE SENTRY DISPLAY - this is your main control unit. It includes a 6' power cable.
2. One RED Button Box with a 6' interconnect cable. You can use standard 2-connector, 18- gauge outdoor/burial wire if you need a longer connection between the RED Button Box and the TEE SENTRY DISPLAY.
3. One GREEN Button Box

The components above are enclosed in an attractive water tight enclosures for easy installation. Also included:

4. Hardware needed to mount one Red/Green TEE SENTRY DISPLAY to a back plate.
5. Two instructional signs to explain the TEE SENTRY to golfers.

1. Mounting posts - 4 x 4 posts work well. Use a length that will bring the tee sentry to eye level.
2. Back plate - a piece of wood or other material, about 12" x 10" in size, which is ½" or ¾" thick -- outdoor plywood works well. The TEE SENTRY DISPLAY will be mounted on this.
3. 120 volt power supply (standard house current) - which must be converted -- or a 12VDC battery (car or lawn tractor battery). The TEE SENTRY DISPLAY must run on 12VDC power; 120-volt power will blow it up. As an option, we can provide a converter which will change your 120-volt supply to 12VDC. This option is economical when the power supply is within 50 ft. of the TEE SENTRY DISPLAY main control unit.

Additional options: We can provide solar battery chargers for your 12-volt battery. We can also supply a lightening suppression module, recommended when you are hardwiring your system.
