27 -The Trillium Compact Posthole is designed with a robust casing allowing it to be deployed via direct-burial without a vault or protective case. It does NOT have leveling feet nor a bubble (**bring your own!**), nor can its mass be rebalanced remotely. The cable is also quite a bit more stiff so may require burial at an increased depth. If installed inside a vault, the cable may also unbalance the sensor if left by itself. The instrument response is identical to a Trillium Compact 120.
