FREQUENTLY ASKED 

QUESTIONS

 

 

 

 

How wide is the scanning beam? 

 

 

The phased array scanning beam on all 

Interphase

 

scanning sonar operates with a 12 degree cone angle 

beam.  This means that the diameter of the beam at 100' 

is about 15' wide.  The transducer operates at 

approximately 200 kHz.  The beam has many unique 

characteristics which allow increased resolution as well 

as increased ranges.  

 

How powerful (watts) are the Phased Array Sonar 

units from Interphase? 

 

Phased Array Sonar does not operate in the same way 

that traditional marine sounders work.  

Interphase

 has 

combined high-tech software with ultrasound technology 

from the medical field and newly released military 

ultrasound technology.  

Interphase's

 ultrasound 

technology is now pending patent approvals.  It operates 

on approximately 420 watts (RMS tested at the 

transducer or 3,200 watts peak to peak) but is channeled 

through eight (8) separate elements and the signal is 

phased via our software.

 

 

 

IMPORTANT NOTE:  All sonar sounders, if more than 

200 watts RMS, have a limited use in shallow water (less 

than 10' from transducer to bottom).  In most cases, the 

need to see forward occurs when traveling from deeper 

to shallower depths.  Forward scanning is possible but 

limited when the water is less than 10' deep.  Some 

clutter on the screen will occur in shallow environments. 

 

  

What type of transducer is needed and what does it 

look like? 

 

The transducers for both 

Outlook

  are available in 

transom or thru-hull configurations.  If you are operating 

an inboard, you must use the thru-hull.  Remember that 

you are measuring ahead from the transducer, therefore, 

placing it as far forward as possible will provide you 

with greater forward range. 

 

The thru-hull transducers are slightly smaller than a 

tennis ball and extremely hydrodynamic (they pass 

through water in a streamlined fashion). 

 

The transom transducers are mounted on a stainless steel 

kick-up bracket in order to minimize the possibility of 

damage if striking a floating object.  The transom bracket 

will 'kick-up' at speeds in excess of 30 knots.  Therefore, 

if you intend on using the forward scan 

at 

high speed, 

you will need to consider a thru-hull transducer. 

 

 

 

How far ahead will I be able to see? 

 

In most cases, forward scanning with the 

Outlook

 is 

approximately six (6) times farther ahead than the depth 

of water.  For example, if you are in 15' of water, you can 

see about 90' ahead of the transducer.  The range is 

limited to 600' forward and 400' in depth.  

 

Typically, if you are attempting to see great distances 

ahead, only targets but not the bottom will appear 

beyond 300 feet ahead, because a flat bottom with no 

targets (rocks, wrecks, fish, etc.) will be stealth or 

invisible to sonar pulses at great distances.  A rocky 

bottom or approaching hazard will normally show up 

clearly on the display, even far ahead.
