Deck-Guard units come with temparary fasteners, including velcro, screws and plastic cable ties. We suggest that you use these fastners while determining where the best location for your Deck-Guard will be. Once location has proven to be effective, we then suggest using permanent fastners, which are available through the manufacture links shown below. We also recommend using marine grade double stick tape to fasten mounts to deck-guard units. Using screws will break the waterproof seal.

Before Mounting...
It’s important to remember that ultrasound works unidirectionally and in a conical manner. Therfore, one unit protects a range of 30 feet by 15 degree vertical range and a 30 degree horizontal range. (see diagram to right)

It is also important to note, ultrasonic waves behave in the exact same way that normal sound waves behave. Ultrasonic waves will not travel through obstacles such as glass or walls, but rather, will be deflected by these surfaces. This is important to keep in mind, as many types of boats have raised structures which will deflect ultrasonic waves. This range will be reduced if there is a structure in the way which can deflect the ultrasonic wave. This means more than one device may be required to adequately cover a boat that is 30’ or under in length.

Set Up:
Setting up your Deck-Guard is simple. For best results, mount your Deck-Guard vertically at the exact level where birds tend to perch. Place the unit within 15 ft. of that area, for motion sensor range. Once turned on, the motion sensor will activate when birds move into its coverage area. Once installed, simply turn it on when you are away from your boat and turn it off when you are on-board. It’s that simple. Deck-Guard works both day and night.


Placement of your Deck-Guard:
Birds like to perch on solid surfaces such as t-tops, dodgers, booms, biminis and rails. To get the most effective results, place your Deck-Guard unit at the same level where they are perching. The suggested areas for mounting are:

• Stern & Bow Pulpits
• Radar Towers
• Fly Bridge
