Built with 316 stainless steel and UV-resistant plastic, it offers weatherproof durability with low maintenance. Available in multiple sizes to fit varied surface areas and provide broad coverage against droppings and contamination.
Key features

- Weatherproof stainless steel and UV-resistant plastics.
- Four diameter options ensure adequate surface coverage.
360° Long Leg Deterrent, 6 Ft

The 6-foot version extends deterrent reach for larger boats and expansive docks. Its robust construction with corrosion-resistant components helps it withstand marine environments while maintaining a minimal maintenance profile. Suitable for both permanent installations and seasonal setups.
Key features
- Increased height for wider coverage around bulky equipment.
- Same wind-swinging mechanism as smaller sizes.
- Sturdy, weatherproof build designed for coastal use.
360° Long Leg Deterrent, 2 Ft

The 2-foot model provides a compact deterrent solution for tight deck spaces or smaller vessels. It shares the same wind-activated, low-maintenance design and weatherproof materials as larger versions, making it a flexible option for boats with limited installation areas.
Gullsweep

Gullsweep provides a straightforward visual deterrent to keep seagulls away from boats, docks, and marinas. While simple in design, it relies on motion and visibility to discourage birds from landing on protected surfaces. Suitable for quick installations without heavy modification.
Daddi Long Legs (4 Ft) by Bird Barrier

The Daddi Long Legs system uses a spider-like design to create visual and motion cues that deter birds, including gulls, from landing on roofs, docks, boats, and HVAC units. It is intended to be humane, minimizing injury while remaining effective from a distance. Installations are designed to be discreet in visible areas like marinas and commercial docks.
Key features
- Spins or wavering motion to deter perching birds.
- Humane, tangle-free stainless steel construction with blunt tips.
- Versatile mounting for roofs, boats, docks, and HVAC units.
Buying Guide: Key Purchase Considerations
- Environment compatibility: Choose materials rated for salt spray, UV exposure, and high humidity. Stainless steel and UV-resistant plastics are common durable options.
- Installation space: If space is limited, compact 2 ft models or low-profile deterrents may fit better than taller options.
- Coverage area: For larger boats or docks, prefer longer legs (6 ft or more) to extend deterrent reach and reduce blind spots where birds can perch.
- Visual vs kinetic deterrents: Long-leg devices use motion and wind, while bird spiders and visual deterrents rely on sight and moving parts. A combination can increase effectiveness in variable weather.
- Maintenance and accessibility: Opt for designs with simple maintenance and easy replacements for worn parts. Consider whether you need removable bases or weighted foundations for stability.
- Humane considerations: Prioritize deterrents that discourage perching without harming birds and minimizing risk to people and property.
- Aesthetic and visibility: In high-visibility areas (malls, crowded docks), choose unobtrusive options like Daddi Long Legs or spider designs that blend with surroundings.
- Cost vs. benefit: Balance upfront costs with long-term maintenance to determine the best value for your vessel or marina.
