To avoid trouble on my flights ftom Belfast to London. I have adopted two ways of getting round the use of kilt pins and sporrans. I have made a kiltpin from a soft toy geko about 5 inchs long. No body has commented on it except children. If the security people object to the small pin that holds it on then i can cut off the pin , give it to them and keep the geko. I have posted a picture. Regarding the sporran it travels in my baggage. It has a 4 inch pin lock on the front and would cause problems. I use a lifeventure travel pouch instead http://www.lifeventure.co.uk/on_the_..._wallets.shtml .
I use it with a seperate belt but it could be worn on a sporran strap.( It has 2 D rings at the top) At the security point I remove the belt and pouch and it goes through no problem on its own.
