Hello all, I am sure glad I found this site. I am building a few ROV's (Shallow and Deep) I thought it might be interesting to add Sonar scanning to my ROV. SO I started searching and ended up here. I thought I would have to purchase an expensive ethernet equipped unit but after looking around the site I see most folks just lengthen the transducer cable using Cat5 or Cat6 cable.
After looking around I figured I could also build a tow fish to help find locations that I want to search with my ROV.
I do not have a Sonar unit, I am starting to look at the different functions etc. But I do want to capture NEMA 0183 or 2000 data to get depth GPS etc.
I have just started reading the site and have a few questions.
When choosing between SI or DI is there a better option? I see the dual units are a bit more expensive. Also all ROV's that go beyond 100M (328 feet) must use a booster for the ethernet cable, Not sure but, but I read that most folks run into a length issue. This booster may help in that department. Link to Amazon https://www.amazon.com/dp/B07DGCP853/?coliid=I14HD4YGUYDBG4&colid=2E8DB8T73Y0UW&psc=0&ref_=lv_ov_lig_dp_it (https://www.amazon.com/dp/B07DGCP853/?coliid=I14HD4YGUYDBG4&colid=2E8DB8T73Y0UW&psc=0&ref_=lv_ov_lig_dp_it)
Let me know if anyone has had success using a booster.
Thanks all
Looking forward to chatting and learning what I can

Hi Joe,
SI gives much more information than DI. The first models with DI used parts of the SI data to show DI (with limited success). When searching for a booster, be aware the transmitted signals are sent through the same wires as the received signals. The voltage may be over 1000 V on transmit. I think it's hard to find a booster that can survive such levels.
