Currently you would be talking well into 3 figures for that sort of policy. The current policy means that the site has to meet certain criteria. I would rather pay less and play at a site that met the criteria than pay a large amount and a bottle blows up near meWould players not prefer to pay a slightly higher premium and be covered for ALL paintball activities, as it stands it seems to me like buying car insurance and only being covered on 12 different approved roads in the country.
And then of course maybe a policy could be arranged so it also covers theft of equipment.
I'm sure if sites complied to the criteria they could make a saving on their insurance too
