More than one diving operator

I have been shark diving at Guadalupe, Mexico, many, many times over the years and was very disappointed that your article “Swimming With Sharks” [Feb. 26] neglected to mention the several other responsible, safe and eco-friendly operators who offer these trips.

They vary greatly in price and accommodations and service. Your article was biased in that it mentioned one operator only.
