Multichannel analysis of surface waves geophones is designed to respond to a certain frequency (e.g.4.5Hz,8Hz,14Hz and 40Hz). While a 4.5Hz geophone is used for most depth. Multichannel analysis of surface waves seismic survey that needs to cover a long linear path quickly may utilize a land streamer.
One common configuration of a land streamer is 24 takeouts spaced 5 feed apart connected with Kooter connectors. A Geo stuff land streamer is a thick strap reinforced that is used to tow an array of geophones. The geophones are fastened to heavy metal blocks that are fixed to the straps. The linear geophone array is rolled along by towing it. The weight of the blocks is intended to provide the necessary coupling to the ground for the geophone to respond. At low frequencies, like a 4.5Hz geophone, this works especially well, if the terrain is not too rough.

A Geode is often accompanied by either two takeout cables or one 24 takeout cable. Takeout is the point where a geophone is connected to the cable. Geophones and takeouts come with a couple of different types of connectors that need to be alike. The two most common connectors are water-tight Kooter connectors and Mueller Clips. Kooter connectors minimize the signal loss in moist environments.
