The kit includes a high capacity syringe and two needles; a fine bore one for injecting air and a large bore needle for injecting oils. To use, carefully attach the needle to the syringe and fill with air or winterised oil. Inject air into the body of the deadbait until it has your required buoyancy, or if you're using oil, inject under the bait skin to promote leak-off.
