I said update - not advice. I don't think we need to worry too much about pulling together peoples experiences. I'll think about how useful it will be. Talking of advice - here's some advice I sent around the team list to last years Huautla trip, I understand other trips have copied it and used it too. Mostly common sense but may be useful to some cavers.
Caving insurance is an essential part of any expedition and it is often a significant cost to individual members. By contrast, if everything goes well on the expedition then it is a complete and utter waste of money, but if things go wrong it can be the best money you have ever spent in your life. Believe me, I have experienced the dark side. Remember you are not really buying insurance for yourself you are buying it to save your caving mates a lot of hassle should something bad happen. Sure, your mates are going to get you out of the cave, but they will be less keen to pay your medical bills or to hire a private aeroplane to repatriate you home. So you need insurance to be a team player and you need certainty that the insurance covers you for the type of caving you are involved with.
Caving insurance usually has two parts to it. One covers you for rescue, medical, repatriation etc and the other covers lost baggage, sports equipment, cancellation etc. You should have the former but may choose to go without the latter. Some folk may find they have 'travel' insurance already which can often covers the latter anyway. This could be on an annual policy with a credit card, home insurance, company insurance etc.
The best place to look for caving insurance are the extreme sport specialists who understand and accept the risk. You don't want to pay for insurance and then find out, when you most need it, that you're not covered. If you are getting a months cover for ?20 from a German motoring organisation, or an Austrian Alpine Club when specialists are ten times that, then you've got to ask yourself whether the cover limitations are too restrictive or if they are going to pay out at all.
I have looked at
www.dogtag.co.uk and
www.snowcard.co.uk who both seem to be popular with UK cavers. There are other providers. One important point to note is that caving trips to Mexico require a higher level of cover than is required in Europe. Therefore if you have an annual policy which is suitable for caving in Matienzo or the Vercors it will probably not be suitable for Mexico. Keep an eye on the excess as usually the lower the price the higher the excess. Most insurers require a medical declaration. It is best to be honest about this and phone the medical advice line if you have any doubts. If you make any mistakes with this, whether they relate to a claim or not, insurers can use this to void the claim.
I hope you find this useful and your insurance a complete waste of money - meaning you have had a safe trip.
