How To Install

All the information you need to prepare for and complete the probe installation is in the Field Guide.

For dealers that are familiar with the cabled Drill & Drop installation technique, please note that the procedure is the same EXCEPT for 2 key points.

  1. The probe should be installed so that the collar is slightly above ground, such that the antenna and battery compartment is not buried
  2. Care needs to be taken during the final push, we recommend using the piece of PVC supplied with the probe
    1. It should be placed over the top and used for the final push
    2. DO NOT use your body weight to step on the cap and drive it into the ground, this works with cabled Drill & Drop, but NOT the Bluetooth enabled design.

We recommend that you watch this video, which shows installation and removal of a Drill & Drop Bluetooth Probe.

(please be aware this was filmed with a R&D prototype using a white cap rather than the final blue cap we are now manufacturing).
