I film my friends and I waterskiing and wakeboarding as a hobby.  The tempurature is about 110 degrees in the summer.  I use hi8 camcorder tape.  So far, everything works out great since I keep the camera in the shade whenever I am not using it, as much as possible.
I am wondering how hot "Hi8" tape can get (or how hot the camcorder can get - it's a Sony DCR-TRV240 NTSC).  The reason I am wondering is because I found a company that sells "video mounting systems" that you mount on the wakeboard tower.  (The web site is www.waterskivideo.com if you want to check it out - they have "demo" videos).  But if I use this system, the camera and Hi8 tape will be out in the sun for a longer amount of time, and I don't know how this will affect the Hi8 tape and  I don't want to damage the camcorder.
Thanks in advance for any responses - Colleen
