[Telepathic Walrus]

Hi, I am trying to get the type of shield that a client is using on the server. using GetPlayerWeaponSlot for secondary doesn't seem to work.
Looking online this seems to be because the shield is classed as a wearable. After trying to search for the specific wearable, using FindEntityByClassname(iEntity, "tf_wearable_demoshield"), I still cant seem to get it working. I need to basically decide if the demoman has the tide turner equipped or not. Is there any way to do this.

Thanks
