Choosing a transducer for a Garmin ECHOMAP UHD2 comes down to two questions: is it on Garmin's recommended list for your display, and does it plug straight in or need an adaptor cable? This guide pulls together Garmin's Recommended Transducer Guide for the ECHOMAP UHD2 cv and ECHOMAP UHD2 sv families, display by display, so you can see at a glance which transducers are listed and where an adaptor is called for.
Source: Garmin's Recommended Transducer Guide (2026 edition, as published in our UK distributor's catalogue). Garmin revises its guidance from time to time, so please contact us with your exact display model and part number before ordering and we'll confirm the right transducer and any cable you need.
Garmin ECHOMAP UHD2 transducer compatibility
Each row is a display in the range. "Direct" transducers are listed without an adaptor; "adaptor required" transducers are listed with the adaptor cable Garmin specifies. Transducers not shown for a display aren't listed for it in Garmin's guide.

Choosing between them
- The guide lists 9 transducers for the ECHOMAP UHD2 cv and 13 for the ECHOMAP UHD2 sv. None of them is flagged as needing an adaptor on either family.
- Listed for both: GT15M-IH (010-12402-00), GT22HW-TM (010-12403-00), GT23M-TH (010-12404-10), GT24UHD-TM (010-12908-00), GT51M-TM (010-01966-00), GT51M-TH (010-01966-10), GT51M-THP (010-01966-11), GT52HW-TM (010-12405-00).
- Listed for the sv only: GT20-TM (010-01960-01), GT21-TH (010-01962-10), GT56UHD-TM (010-13073-00), GT56UHD-TH (010-02732-10), GT56UHD-THP (010-02732-11). That includes the GT56UHD all-in-one family.
- Listed for the cv only: GT20-TM (010-01960-00). For the sv, the guide lists the other GT20-TM part number, 010-01960-01, instead.
- If you have a cv and are looking at a GT56UHD transducer, it isn't listed for the cv family. Check with us before ordering.

Frequently asked questions
Do I need an adaptor cable for my ECHOMAP UHD2?
Not for the transducers on Garmin's list. None of the transducers listed for this range is flagged as needing an adaptor. If you're looking at a transducer that isn't on the list, please ask us first.
What if my transducer isn't in the table?
If a transducer isn't shown against your display, it isn't on Garmin's recommended list for it. That doesn't always mean it won't work, but we won't recommend it without checking. Contact us with the display and transducer part numbers and we'll look into it.
Does every display in the range take the same transducers?
In Garmin's guide, yes within each family: every display in the ECHOMAP UHD2 cv and ECHOMAP UHD2 sv families has the same list. The cv and sv families have different lists, so check which one you have.
Will you fit the transducer for me?
We supply and advise on Garmin transducers and adaptor cables; we don't fit them. Installation should be carried out by a qualified marine installer or by you as the boat owner, following Garmin's installation instructions.
How do I make sure I order the right one?
Send us your display's exact model and part number (it's on the box or the label on the back of the unit) and how you plan to mount the transducer. We'll confirm the right transducer and any adaptor cable before you order.
