Room Surveillance Bugs

This 2-transistor 3V ?bug? gives exceptionally clear and stable performance given its low price and simplicity. And because it has a lower output power battery life is significantly extended.
'MTX' Miniature
3V FM Room Bug
*

MMTX offers excellent performance in a very compact package. It rivals many competitors products selling at 10 times the price! No surprise then that it's our best selling bug and is used by professional detective agencies worldwide. Measuring just 25 x 15mm and needing no aerial wire, it is small enough to hide just about anywhere.
'MMTX' Micro-Miniature 9V FM Room Bug
*

Vastly improved design is more powerful than our 3V MTX room bug and slightly more refined than our MMTX 9V room bug. This circuit uses 2-transistors with the tank oscillator coil built onto the PCB for extra stability in operation. There is a choice of two output powers offering a choice of greater range or greater stability.
'MRTX' Miniature
9V FM Room Bug
*

The HPTX is our most powerful room bug to date and really is an impressive performer. HPTX has an audio stage and two RF stages with an RF transistor in the final stage. It provides both a clear and stable output signal thanks to the extra circuitry employed.
'HPTX' High Power
FM Room Bug

We get asked on occasion, "Why is there no box for some of your bugging devices?". Here are a few of the reasons:

  • It saves you money

  • a box does not enhance performance

  • a box makes the bug bigger and harder to hide

  • It means you can afford to "loose" a £15 bug in the field. Would you want to loose a beautifully boxed bug that does the same job but costs £150?

We also get asked "Why are your prices so low; are they inferior quality?"

Well, you would expect that spending £150 on a bug would give you a high quality product. Quite often you are just being taken for a ride and inside the packaging is a circuit not much different to ours. We just dispense with all the fancy packaging and sell you a very reasonable quality product at a very reasonable price.
