Sorry for the late update and thanks for everybody's input. I purchased a Pelican 1615 case for my Detector coils and shafts, scoop, scoop handles snorkeling gear everything fit perfectly in it. This case will last and be used for a long time. Hawaiian Airlines does not allow any lithium Ion Battery's in checked baggage, none , noway, nada. Sucked pulling the head out on my EQ 800 and putting it in my back pack, with the shaft attached. Couldn't unscrew it in a timely manner while in line with the allen wrench. I know somebody said put it in my back pack, I can hear you laughing at my pain. It worked though. First day was raining and windy, and the surf was really choppy, so were day 2, 3, and 4. Day 5, I was able to put one good day in and parts of day 6. I found a silver earring with a fake turquoise stone, and a penny. The water and the beach were warm and I just had to work with the chop and get some OJT. This is my very first time detecting in water and in the surf. What an experience! Cleaned and rinsed all my gear up at the rinse station. Packed it away. I went to go use my 800 yesterday and it was singing and pinging, it just wouldn't settle down. then I notice water behind the screen. So here starts another saga. Sending it to Minelab tomorrow. Oh Steve H, the Service Center Phone numbers you have somewhere on this site, in another post are Golden. Thanks!
