What guarantee is there that Project Lifesaver will locate my loved ones should they become missing?

We would like to say there is a 100% guarantee; however, there is no such thing, regardless of the technology or method utilized.  It must always be remembered that when dealing with people, each situation will be different.  Project Lifesaver does have the most successful record in the world. This has been accomplished through a combination of training, methods, procedures and the latest technology which is tested often in real world situations. The best protection is to have trained personnel with the latest equipment available, respond and conduct these searches. The success record of this approach speaks for itself.
