Housing (400-1200) is designed to accept 1.25"
diameter x 15" long beacons. It does not have space for
the nylon sleeve. In "heavy metal" beacons housings
such as this, a lower frequency may be more effective.
1. Wrap two to four layers of electrical tape (4) in the
positions shown (or wrap the entire length of the
beacon).
IMPORTANT: Ensure proper frequency is in use for
present conditions.
Remove Beacon from Tool Housing
IMPORTANT: Remove beacon before mud in beacon
chamber hardens and locks beacon into housing.
1. Remove beacon from tool housing.
IMPORTANT: If beacon will not come out, do not
use force. Try soaking housing in water until dried
mud inside housing softens. If beacon still will not
come out, contact your Ditch Witch
advice.
2. Clean beacon and remove battery.
3. Wash and lubricate tool housing.
