Hey guys, finally got round to sending my detector back to the states for a service for "self cal" and laser alerts every time I hit biggish boost, trust me nothing worse.

One time fee of US$59.95 gives a full service (A$130 including return freight), they replaced antennae, tuned and check with latest software, supplied new mounts and power cord.
The difference in this detecter is simply astonishing, cannot believe the difference in performance on multi novas after the tune up!! well worth it.
Thanks Jez!

Oh yeah, how nude do you feel without a detector for a few weeks........
