Lowrance Hook2 Triple Shot

[dgarland10]

I am a FF novice, and have learned a lot here including a bunch of great info from Chris B. My Hook2 triple shot often does not display depth. If I turn it off and back on sometimes it displays then or will display for a few then stop. Any ideas on how to remedy this?

I had a Hook2 (5") and had the same issue. It was due to depth. The unit itself is rated to about 600 feet in freshwater , using the 200khz frequency). In saltwater that's probably more like 400 based on the bottom composition.

I would frequently lose depth reading when going over canyons I think the deepest I ever read was about 450 in saltwater with that unit, but usually it would start going blank around 350'. You can probably get a lower frequency xducer for it but you will have to reach out to lowrance and see what will work.

Btw I was using the splitshot/HDI (200khz xducer) not the triple shot.

Try applying a generous blob of dielectric grease on all connection points. It has been a game-changer for me on many occasions.

It most definitely works....

I have heard not to put dielectric grease on male plugs? How do you guys recommend applying?

Generously. I put a blob on either the male or female end, make sure it is lined up properly for connecting, and then firmly press the fittings together. The access grease will ooze out of any tolerance gaps in the connection, that might otherwise be subject to water ingress. After connected, the excess that oozed out can be wiped off with a rag.

A larger automotive tube of dielectric grease from amazon is the most economical purchase.


Note: It has been brought to my attention that the Lowrance Hook2 does not have a bayonet locking plug to connect the cables to the unit. Without the bayonet locking mechanism, dielectric grease cannot be applied in the generous manner that I have used on other Lowrance, Garmin, and Raymarine units. Reportedly the hook2 cables just plug in with no means of locking them connected. Due to the less permanent plug in system, the excess grease reportedly prevents the plug from staying connected to the unit.
