That often ends in regurgitation! I was on a boat outside Clearwater Beach with my 10x42 Nikons and another person on board had some nice 16x50s or 60s. I suggested she look through mine. She was pretty amazed at how well she could see and that everything looked so clear and bright. I looked through hers... man. I told her that I'd prefer to have had 8x42s and that 7x35s and 7x50s were the marine standard.
