Installing Spikes on a Tromino Seismograph
Many users of Tromino ENGY and Zero units have complained that the longer, pointed studs seem too tight to screw into the bottom lugs of the units. This is due, in part, to very tight tolerances when the lugs are tapped for the threads on the legs. However, there is another possibility which you must guard against and that is cross-threading.
Our new 12-channel hydrophone string is a skinny thing!
This new, slender hydrophone string is just the ticket for collecting seismic data in a narrow borehole. With a maximum outside dimension of only 1.25", the cable will easily fit into any 2" ID borehole. The cable is outfitted with (12) HTI-96 hydrophones (unamplified) at 3-foot intervals and has a 250 foot lead terminated with a Geometrics-type Bendix 61 connector at one end and a small stainless stress anchor at the other.
EXI To Discontinue Renting 200 mhz Radar Antenna
Due to diminished demand and the advent of the highly-capable 350 mHz Hyper-stacking antennas, Exploration will soon discontinue carrying the GSSI 200 mHz analogue antenna.

Tromino Zero Adds Low-Cost Passive Seismic Option
Due to increased demand for the Tromino seismograph, EXI has added two Zero units to the rental inventory.
Passive Seismic Surveying with Tromino
The application of passive seismic measurements (VS/VP) is gaining in popularity due to the availability of small, portable all-in-one seismographs.
UCL to MARS
In 2017, we had the pleasure of working with Elke Mergny and Crew 178 from UCL to MARS program in their experimental stay at the research station in Utah. A recent article in National Geographic (https://www.nationalgeographic.com/photography/proof/2018/05/mars-on-earth-nasa-training/) reminded us of that project and we asked Elke if she would write us a description of her time there. She graciously provided us with the following account.

The Search For A Concealed Impact Crater
Professor Dr. Donald Stierman and student Eric Armstrong from the University of Toledo, Ohio (UT) recently used the MOHO Tromino passive seismic system from Exploration Instruments (EXI) to try to detect the bottom of a suspected impact crater located in Seneca County, Ohio.
New Inventory: GISCO Radio Trigger Link
Exploration Instruments has added a new GISCO Radio Trigger Link to its rental inventory. The package has two modules, each employing its own radio, to connect a trigger associated with a source (hammer, AWD, Scorpion, etc.) to the recording seismograph. This system eliminates the need for the common trigger extension cable which...
