Good afternoon Dan in FL,
Thank you for your inquiry.
The TZT2 can use the 526TID-LTD/12 or the 526TID-LTD/20 for RezBoost but not for Bottom Discrimination.
Please keep in mind that the low profile transducers can be more prone to turbulence related issues because the do not use a fairing block and they do not protrude from the hull much. RezBoost or standard mode could have performance issues if the water is turbulent as it goes over the transducer face.
