Jim M at B.O.E has produce a video [about the new AIRMAR TM260 transom mount SONAR transducer]. It's the mother of all transom mounted transducers.

Tom--Thanks for the link. I have a few observations:
--the Airmar TM260 is enormous. That is a huge transducer;
--never wear open-toe shoes when doing a video demonstration;
--Jim from BOE does not look like I pictured him.

The specifications for the Airmar TM260 transom mount transducer:
--Broadband Ceramic Technology:
--Crystal clear image detail and resolution
--Distinguishes individual fish targets and
fish tight to the bottom
--1,000 Watts
--Depth and new fast-response temp. sensor
--Transom-Mount, Urethane Housing
--50/200 kHz
--Q at 50 kHz—8
--Q at 200 kHz—8
--12 m (39’) cable with OEM connector
--Beam Width:
----50 kHz—19°
----200 kHz—6°
--Maximum Depth Range:
----50 kHz—529 m to 735 m (1,800’ to 2,500’)
----200 kHz—206 m to 294 m (700’ to 1,000’)
--Boat Size: 8 m to 12 m (25’ to 40’)
The low values of the "Q" refer to the natural resonance of the transducer and how much it tends to ring after it has been excited by the SONAR pulse. In general a low value of Q is believed to permit greater sensitivity and resolution of echo signals. As a comparison, the Q of the smaller P66 transom mount transducer is listed as 24 to 30.

It's been a few months since the new Airmar TM260 transducer has been available. This transom mount high resolution, high speed transducer would seem to be the perfect solution for Whaler fishermen, eliminating the problems with trying to shoot through our foam filled hulls or cutting a big hole through the foam and hull.
Has anyone out there installed one on the transom of his/her Whaler? Please report results and link to photos if any, especially showing deep (>100 fathom?) operation.
Thanks!

Sorry only followed a few posts on tidalfish as one guy there has been trying out the TM260 since mid September and in particular with Lowrance HDS units, plenty of screen shots including shallow water.
Also some new Lowrance sidescan shots :)
I think Jim M at B.O.E also supplied the equipment
Regards
Steve
