I was just woundering if anyone has any experence with these I have a friend that can get me hooked up with thier 900mhz receaver, belt clip sender unit and a lav for around $100 is it worth it?

Simple and short answer...

>is it worth it?

Absolutely not.

Its probably okay as an IFB where audio quality is not a concern, but if you need it for real audio you will need to try something else.

If money is the problem, you might want to try VHF units which should cost about half of what UHF system will. However, these are more prone to interference than UHF systems have. If you can live with that, you may have your solution.

thanksfor the input
