HM Series HM-400 4 Place

A portable voice activated intercom system which can be taken with you when you leave your aircraft is suitable for connecting four headsets. Operating from one or two PP3 batteries, it can provide up to 48 hours of maintenance free use.

Provided with the intercom is a lead to connect to a cigarette lighter, and another for connecting to a tape recorder etc for playing background music as you fly. In this mode should the P.T.T. switch be pressed, the music is cut off. The tape recorder can also be used to record conversations or commentary on your flight as it progresses. This attractively priced unit has many of the features of other more expensive intercoms.

Brilliant! Brilliant! Brilliant! What service!! My GPS went wrong. After a phone call you got me a replacement and took my faulty unit back via courier. All within 24 hours. I just couldn't ask for better service. Please thank the lady I spoke to on the phone, she couldn't have been more helpful. This takes all the worries away from mail order.
