Default HDS-7 transducer for Great Lakes use

I am considering adding an HDS-7 to my Scout 202 Dorado. I fish Lake Michigan for salmon and trout, typically fishing water 60 to no deeper than 400 feet deep. Fish can be suspended just below the surface to belly-on-the-bottom and anywhere in between.

Any insight as to which transducer would be best for my application?

1) Lowrance 83/200 khz transom mount
2) Airmar P66 50/200 khz transom mount

Thanks for any insight you may have. I have learned a lot over the years lurking here.

I have both Lowrance 83/200kHz and B60 (same transducer element as P66) which I use with HDS. And no doubt you should go for P66, or even better B60 which will give sharp images at any speed.

I am using the stock 83/200 mouted to shoot through the hull on Puget Sound for Salmon. Coho usually in the upper 125 ft in 300 to 700 feet of water. Chinook down to 250feeding on the bottom. No problems - works fine. I suppose I could refi my house and spend mega-bucks for a "THT Seal of Approval" Airmar 250 kilowatt transducer, but so far I haven't seen the need.

The P66 will be a good choice over a OEM transom mount and the B60 having the same elements as the P66 will be an improvement due to it mounting location..funning in cleaner water.

Every level of increase in the quality of your transducer will give give you added performance for your sonar.
