[DeTomaso] SuperEyes borescope review

[Jerry Knotts]

Asa,

In taking your advise, because I can never miss out on cheap, I 
purchased one also.  I think with an additional purchase of:

http://www.amazon.com/dp/B00CBKFJ9Y/ref=pe_259560_33682720_pd_re_dt_dt1

You will find the scope easier to use.  I is a three mirror set that 
affixes to the end of the borescope and provides mirrors at 3 different 
angles to deflect the lens and LED light.

Thanks, YMMV,
jerry
