Sonarmite/SonarM8 User Manual
Introduction
The Sonarmite and HydroLite-TM were designed to be an ultra-portable survey-grade,
self-contained bathymetric survey system. The internal battery, blue tooth and easy
integration make it most popular with Survey and Engineering companies.
Seafloor Systems partnered with Ohmex UK back in 2006 while we were asked to build a
replacement survey kit for the US Army and Navy dive teams. The Sonarmite was the
perfect fit for our HydroLite-TM kit at the time. We cut the Army's system down from 3
cases to one pelican case; also the ease of operation was appreciated.
As time went on we began building the systems in our Northern California facility
upgrading as we went. Today's system has longer battery life, stronger blue tooth, Mil-
spec connectors and caps and much more. Thanks to Hypack, Trimble, Carlson, Leica
and Topcon for writing drivers to make logging easy for our customers, this has really
boosted popularity and sales worldwide. We now build all of the systems for North and
South America as well as other Continents.

To do this you would get a water temperature from mid water column and refer to proper sound velocity table for fresh or salt water.

Insert transducer connector to Sonarmite control box, look for blinking red light. 3. Connect to terminal program. a. SENA BTERM via Bluetooth: http://seafloorsystems.com/pdf/sena_bterm.pdf...

- Page 8 returns. To measure mud thickness and avoid litigation on wrong results the surveyor should use equipment specifically designed for geophysical measurements such as a sub-bottom profiler, penetrometer, seismograph or a simple bottom sample grab Is a Barcheck required ? Many older technology echo sounders needed to "Warm up" before they became stable, in addition to their internal frequency/timing circuits varying with ambient conditions the physical parameters that effect speed of sound in water also varied with location.
- Page 9 a weighted tape) and these points used as a reference throughout the duration of the survey Should Pitch/Roll angle be applied to the depth ? Many surveyors assume that sonar is like a laser being shone through the water and that the distance measured should be assumed is a hypotenuse measurement to be trigonometrically corrected by any Pitch/Roll angle that has been measured.
- Page 10 either heavily averaged to show a smooth transition in numeric depth values or are optimized to show the shallowest depth seen in the particular beam area. Similarly survey echo sounders make efforts to remove anomalies such as fish swim bladder reflections from the measured data. Do I need more pings per second ? Assuming the pings all return good values the advantage of more pings per second is that the survey boat can travel faster and therefore cover much larger...

All of the above parameters can vary considerably in any particular water column but the assumption made with a single beam echo sounder is ..
