    Where and how do you place your transducer to get that great image ,with that clearity at 53 mph ? I'm assuming those are fish on the left picture, correct ? I don't get fish at 5 mph ....

    Shoot thru P75M - Medium CHIRP
    Much better than P79 - IMO

    I have seen 45mph with CPT-100DVS on the transom of a Warrior.

    The CHIRP transducer is a low (25W) transducer. Kayakers have said it will shoot thru a thin kayak hull, but not recommended for a glass boat.

    No, aluminum hulls are a traditional taransduers worst nightmare.

    Working on it... it’s a sample that we had - not production with a Raymarine plug yet.

    I have tried a P79 on a aluminium hull 6 mm thick, no problem up to about 20 knots at 10 m depth. If the metal is homogenous and under 8 mm thick it will work somehow but not as good as on glass hull.
