Hi RobP, welcome aboard. Enjoy your stay on the forum.
I have a Traser 6502 and it's rated to 200 meters and I think the 6500 is rated to 30 meters and 6502 and above are 200 meters.. The 6500 does not appear to have tritium on the second hand as the rest of the 650x series do. Also the auto 2824 series appear to be rated to 100 meters.
