We have a Deeper DP4H13S10 sonar, and the goal is to increase its signal range.
The original Deeper Range Extender costs about €195.
How can we solve this using what we already have? And even make it better?
It’s very simple.

And you want to solve everything here and now.

Lack of thermal interface, resulting in overheating and desoldering of the contact.
If you order the same one - price, waiting time and similar result.
