Frustrated by casting small baits to crashing tuna just out of range? Pick up a pack of biodegradable Disinaweights. They provide the heft for extra casting distance, but the tape holding them together falls apart upon contact with water, allowing the weight to drop off the line to let the bait swim unhindered. Non-toxic Disina-weights weigh two ounces and sell for $1.89 per package of three. Angler's Science, Balboa Is., CA; (949) 412-2850; www.anglersscience.com.
