Will the PiranhaMax series use the same transducer as my 597 did? I saw that it uses an XNT 9 28 T, and I think my 597 uses an XNT 9 20 T. Looks like the frequencies and beam angles are different. Is that going to make the Piranhamax incompatible with the XNT 9 20 T?
Are there any other cheap options you guys might suggest for either being plug & play with the equipment I have or being cheap enough to start from scratch with for just 2D sonar up front?
HB 597 at the bow has died. I have an HDS-5 flush mounted in the console and an HDS-7 at the console on a RAM mount that I can flip around when I'm fishing on the front deck. But I still like having depth at the trolling motor, which was all I really used the 597 for. So I was thinking I could buy a cheap 500 series unit on ebay (head unit only) but I just searched and was shocked at what those idiots are paying for stuff. I got my 597 on closeout in October of 2010 for $300, and I just saw a bid for an open box 597 for $385 on ebay. That unit has been discontinued for 5 years!
I still need to diagnose mine to see if it's the unit or transducer. But assuming the transducer isn't the issue, I'm in the market for a new unit.
Anyway, I assumed pretty much any 500 series unit would be plug & play with my standard 2D trolling motor transducer, standard power cable and 500 series mounting bracket. But after seeing the ebay costs, I started looking for a cheaper unit and that's how I came up with the Piranhamax 197.
Transducer do fail, so do power circuit fuses. Additionally the connection of the pins in the plugs in the cable collector can get misaligned with the display receptacles.
There are dual beam sonar 500 series, single beam sonar 500 series, Down Imaging 500 series and Side Imaging 500 series. They do not all use the same transducer. The DI version cannot use the 2D transdcuer you have.
The proper trolling motor transducer is the puck XTM 9 20 T.
The XNT 9 28 T is tuned to 200/455 kHz. Your 597 2D unit has 83/200
kHz. The PiranhaMax 197 is a 200/455 kHz unit.
