It might be worth checking with the MoD about when you can go there as access is denied when the range is in use (ive been led to believe). I fish this area from my boat occasionally, last year in may i watched a large shoal of sandeel swim under the boat, only seconds later they shot back with a group of large bass in pursuit. These were'nt schoolies and as soon as they got under the boat they spooked and shot back in the direction they came from. There wasn't a fish under 5lb amongst em!! I tried a plug for 20 mins or so but nothing. Ive also had some nice plaice from the same mark (biggest 4lb) but further along towards the beach on the drift.
