Try Betty and Nicks in Seaside Park. It is located at the entrance to Island Beach State Park and has all the hot info for that day. Additionally, they carry great products, including great flyfishing equipment. It is the home shop for Bob Popovics and has a lot of his stuff as well.
Brandon, depends on what you mean by best tackle. Betty and Nicks in seaside park was always number one in the area but I believe with the passing of owner John Bushell this October the shop will lose its personality since his son is not very good with customers. Also, their reports have been somewhat long tooth lately. As far as fresh bait shops no one beats the New Dolphin in Seaside Park, owner Bill Clinton has been supplying the most reasonable, freshest bait for years. Up and comming in the area is Murphy's Hook House Toms River handles very nice selection of surf lures.
There are good bait shops all up and down Jersey If you know more specifically what area I can send you a list. If its surf fishing you're after Island Beach State Park ( $50.00 to get 3 day beach pass, $5.00 walk in) in Seaside Park ,Jersey has Hook & Tackle on route 37 before seaside( 2 miles before look on your right) easy to miss and in Seaside is New Dolphin And Betty& Nicks If your looking for the best selection of equipment and fresh bait, Dolphin and Betty"s will fill the bill. Previous post was right about Betty's, the son has delt with many jerks having striper fever and has lost the customer service touch but thats not new either.
