I dont know if this has been discussed on here before but about the only thing I didn't like about my new swarovski cl companion binoculars was there was not a good way to get them connected to my binocular chest pack. So I thought I would share the "hack" I came up with. The swarovski el line shares the same strap connector system as the new cl companion. So I purchased the strap loop connectors they sell for the el line from BH photo. However the pin on the el is a little longer so the spacing is to wide to get the pin to lock in. So what you have to do is bore the pin hole out on the plastic strap connector with a 1/4 inch drill bit. You probably are not even taking out a 1/16th but it allows it to seat much nicer. Then with a piece of sand paper sand the back of the connector down probably less than 1/16th. I just laid out the paper and rubbed the connector on it and kept checking fit until I could get the pin to lock in. The whole process took less than 15 mins and cost me around $10 for the strap connectors from BH photo. If this interest you or have any questions you can message me.
