2-Way Boat Alarm

Demonstration video on the website is mis-leading. Once alarm is triggered by vibration there needs to be a subsequent event to activate the 125sb siren. The video gives the impression the siren goes off upon initial vibration. Battery cover on transmitter does not slide off easily. Suggest buying a spare transmitter. Unit was easy to install.

Super Product

I am well pleased with the alarm system. However the package appeared to have been previously opened and spilled out in the shipping box. It was missing the printed directions.

Great Product

I like how I had the option to hook it up to the deck lights to flash. So if when the alarm goes off. Now the lights with flash right along with it.

Nice product.

Product works as advertised. Very happy with T-M customer service. Ashley assisted me with an issue I had quickly and professionally. Couldn't be more satisfied. I do wish the remote was a little more substantial. It feels very delicate and I have concerns with it's longevity. The installation manual could contain a few more details.
