The perfect tool for pushing the grommet holding your dynamo wishbone into your speargun rubber.

Don't get caught out on a days diving without a spares kit or you could become just a spectator.  Have everything you need to repair your gun in your bag.

Please use with caution as you will be putting a lot of pressure through this tool very close to your hand - particularly the skin between your thumb and index finger.

 Try to lubricate the grommet or rubber end with some food grade silicone or washing up liquid.
