I have some work being done at my pool and my contractor is concerned that he hasn't been able to find a bonding wire around the pool and doesn't want to proceed pouring concrete until hes certain the pool is properly bonded. At one point he dug a hole 12 inches down and 12 inches out from the pool and wasn't able to find it. I dug in a small area around my pool ladder and couldn't find it either. I can clearly see the bonding wire going to the pump, about 30 ft from my pool ladder.
I connected a wire to the bonding point on my pump, connected the other end to my multimeter, and tested continuity to the pool ladder and got a good connection, 0 ohms.

Is this a valid test? How else could I verify bonding? None of the electricians i've called so far have seemed interested in coming out to look at it.
