I've been using the ACE 250 for about 18 months now and it does a great job. Now I need a good machine for the ocean. I can't make up my mind over the Sea Hunter or the Infinum. Most of my hunting will be on the beach or wading, but I do have a PADI card and would want the option to use it when diving. I've even considered the White's Dual PI. Any suggestions from you experienced beach hunters.
