Thank you for viewing! This product is an air pump (bubbler) useful for fishing and other activities! 【Product Contents】 Air pump (bubbler) body Tube Air stone 【Product Specifications】 Size: 12cm long, 8cm wide, 4cm thick Weight: Approximately 158g (body only) Power supply: 1 x D-cell battery (sold separately) 【Product Description】 Have you ever had the experience of catching small fish for live bait, only to have them all die or become weak due to lack of oxygen? By using an air pump, you can supply oxygen to the fishing bucket or bag, preventing fish from dying due to oxygen deficiency! There is a switch with weak and strong modes, but even the weak mode provides sufficient air! A hook is also included that can be attached to the side of the bag, making it less of an obstruction. This product runs on one D-cell battery. Recently, lithium battery types have also appeared, but they have questionable safety due to the high possibility of rupture from high temperatures, submersion, or impact, which can damage fishing gear or the interior of a car. Dry cell batteries are safer and are recommended for outdoor activities such as fishing. A rubber packing is also installed inside the case to prevent water ingress, providing good water resistance. Also, the operating noise is not quiet, so it is not suitable for indoor use. If you have any questions, please feel free to comment.
