Humminbird7400901 MHX XNPT Portable Mounting Hardware Kit

I'm using it as a portable unit for a fly in fishing trip in Canada. I got everything assembled and tried it out and it works great.

It works well

I cracked the sonar holder to my hummingbird fish finder but these spare parts fit perfect. Up and running again, very happy that it saved my fish finder.

A suction cup mount clearly isn’t going to be as strong as a permanent mount! Duh!I went on a week long remote fishing trip in northern Ontario, we used the outfitter’s 3 aluminum boats. I was back and forth between all three boats and had to take my transducer with me between each of them. I think it mentions in the instructions that this mount is for stationary/slower speeds only. It held on really well even when the boat was on a plane at high speeds. I would recommend that before each outing that you take the transducer off and stick it back on the transom of the boat - just in case it’s lost some of its suction. As well, I took 3 zipties and made a safety tether so that if the suction cup failed the transducer wouldn’t get chewed up by the prop. Failsafe! <—- be smart!A week or two after that trip I took the same transducer to a lakeside Airbnb that had an older cedar strip boat. The suction cup had no issue staying attached to the transom, but of course to be safe I used a ziptie safety again. Don’t hesitate buying this, unless you’re planning at travelling at high speed over long periods of time. I was actually pretty impressed with how well it stayed on

I got this to make my locator ice fishing box usable for a Canadian fishing trip. While it did work similar to the ones our guide provided, the suction cup failed several times while running the outboard. I would have to stop, reel in the transducer, roll up my sleeves, and reattach the suction bracket to the boat. The bracket may be a bit too heavy combined with the transducer I need to be efficient.
