I have been using the Nikon Laserforce Rangefinding Bino. Since last year, the focusing ring keeps losing grip. It cannot focus as the result. I managed to "fix" it but the issue happens again. Trying to send it to the Nikon for warranty. the website asks for the receipt and warranty paper. which of course have been lost long ago. I would like to have the issue fixed by paying a local repairperson.

Thank you in advance if someone can point me to the right person in VI.
