Re-fillable air horn,

Our expectations & reasoning behind this.
Basically a non-lethal animal deterrent that should be legal to possess in most countries.
A portable re-fillable air horn that uses a bike or car tyer pump to reprime, car tyer pumps usually have a gauge so may be the best option, but for lightweight excursions away from the van, there is a bike pump supplied with it.
