I’m a Garmin user so slightly biased, but I’ve had a chance to use my buddy’s ML2 this winter. It is a significant upgrade over ML1, but that’s only because ML1 was so poor. The mega live 2 has an image quality somewhere right in between Garmin’s LVS32 transducer and the LVS34 transducer.
A few of the downfalls I noted: It barely fits down an 8″ hole. You have to angle the transducer perfectly to get it in. When you first put in the water it takes at least 5-8 seconds to register since it stops transmitting when out of the water. Not a crazy issue, just annoying when trying to move fast.
It doesn’t really move the needle past the latest Garmin products, but it does provide an upgrade to the hardcore Humminbird users.
