I replaced it with an Airmar TM260 and I could not be happier. The new Airmar TM series transducers have performance equal to their Thru Hull counterparts without having to drill a hole in your hull. I suggest you check out the TM series.
    We are talking about shooting through the aluminum not drilling a hole in it.

    Vexilar and Garmin both make "in hull" transducers, I think what MM has discovered and turned me onto is the fact that a transom mount ducer mounted in hull does indeed work. I can say that proof positive. However it may not be the best choice for you as I have a fairly basic setup. And in a dedicated ocean boat you may want better more powerful equipment.

    This is just one of garmins offering

    There is a wealth of info and choices and my knowledge is very limited on this equipment

In fact this is the prefered method to test a location before it is made permanent with epoxy.
    The op is looking at a totally different application than you are. He's looking at getting the best possible performance out of his sounder and is looking at spending $800 on the transducer. How the transducer is mounted is critical to it's performance, and being able to differentiate fish at 100 fathoms is an entirely different balgame then showing 35' depth in a river. Getting the best performance out of his combo is critical to him making a living.

    Contact Airmar, they have great customer service and will advise you as to the best transducer for your application, how you should mount it, and how you shouldn't mount it.

    Personally I don't like holes in a hull below the waterline, so I'd lean towards a transom mount if you have a spot you can mount it that has non turbulant water flowing to it. Friends have been very pleased with their airmar transom mount with their Furuno, but it is a 600w setup.

    If you have a tenuous grasp of reality, Alaska is not for you.

    Shark Bait,

    My assumption was that a thru hull was a better unit, more able to read bottom on plane in deep water. That has now been challenged. I plan on calling Airmar when I get a chance and asking about all the above options: thru hull/in-huill/and transom mount. As usual this forum opened my eyes a little bit more.

    I give a big thumbs up on Airmar stainless through hull ducers. Last couple boats have had the flush mount ones. Reads bottom at hundred plus fathoms at thirty knots. Love the 1kw power.
    Purchaced a two year old boat this spring, Airmar ducer was bad, replaced it with the exact same one, 1200 bucks.
    I blame the failure on the install. No isolation bushing and no sealant.

    Ebbtide,
    If you are still looking for good transducer then try this Airmar SS264N or SS264W. I have SS264N on my 29' boat with 12 degrees tilt and I can read bottom down to about 2700', deepest spot in the PWS. at speed up to about 35mph it will read depth down to about 1000'. This is very good setup for deep sea fishing and shrimping, it will give you very clean bottom images down to about 1500' at low speed.

    Still looking. I will probably start researching this about Jan when things really slow down. Thanks for the info though. I will look into these particular models.
