Sure, it's a good idea to bring your detector. Daytona is a great beach and it has usually produced good finds most of the times I have hunted it - being from Miami, I don't get up that way too often. During the summer, there usually won't be a great number of good targets (unless you are lucky enough to come across a washout or cut of some kind), but like the old addage says, you are after quality not quantity most of the time. One target can easily make your day if it's gold. It does take some patience to find the goods at DB. Goldnugget is right on about parking - don't think about parking illegally to save a buck. Don't forget your change since it's all metered parking there - no freebies. Cops and land owners in DB can be real jerks - they love to tow you or at least give you an expensive parking ticket if you park in the wrong spots. Also, having a good strong long-handled sand scoop is a good idea since DB's sand is really heavy and hard packed and targets are often really deep.
Good luck and hope you get some gold.
Thanks,
Mark
