Sorry, I need to clear that up. Spotted Eagle Rays. Not Manta Rays. I have seen 4 Manta rays in Aruba over the last 20 years and quite a few in the Maldives. But only Sting Rays and Spotted Eagle rays here in Roatan.
I just googled boot dryers. Mine are a plastic base with 2 tubes coming up. You place the pair on the tube, upside down and the heat circulates around and in 2 or 3 hours, they are dry, dry. I will not go on a dive trip without one any more.
We are on the plane tomorrow so our dives are done. Coco Resort is a first class operation and we will be back.
