I'm thinking about getting a portable fish finder for trips to Lake Como. I've seen some pretty compact Garmin and Lowrance models, but I'm not sure if it's worth spending 200-300 euros or if something cheaper would be better. Which ones do you guys use?
How often do you actually plan to use it? 🎣 If it's a serious passion and Lake Como is your area, Garmin and Lowrance in that price range will pay for themselves in peace of mind - decent batteries, screens readable in sunlight, and reliable sonar. If you're using it now and then, maybe a basic model costs less and it's no big deal if I leave it in the boat under the sun. One trick not many people mention: before buying, try looking for models from a year or two back from the same brand - often it's identical hardware but an amazing discount 🤙
For Lake Como with that budget, the Garmin and Lowrance models you mentioned are genuinely solid if you fish with some regularity - a decent screen and the right frequencies really do make a difference in picking out the bottom and spotting fish. If you're just starting out or only go a few times a year though, a basic model for 100-150 euros will work just fine for reading depth and general movement, then you can figure out if you really need to spend more. I'd go with the Garmin if you fish often and want something reliable, but it really depends on how seriously you take it - Lake Como isn't bad even with modest gear, as long as you don't expect pro-level results.
Garmin and Lowrance at that price point pay for themselves right away if you really fish Lake Como consistently - they're rugged and read well even with the depth variations that lake has. But there's a detail a lot of people overlook: check that the transducer is compatible with your fishing ecosystem. If you're already using apps like Navily or offline maps on your phone, a unit that syncs with those saves you time and you don't have to watch two different screens while you're looking for the right spot.
The real trick though is going to see them in person at a shop before buying online. Try the grip, see if the screen is readable in sunlight (that's not a given here), ask the shop staff which frequencies (50 and 200 kHz) you actually need for the species you're after on Lake Como. You might even find that someone has an older model on sale at a discount but still works great. But if you use the fish-finder rarely, honestly a basic model for 100-150 euros does the job - don't waste money on it.
If you really want to understand what you're fishing on Como, don't just look at the device's price but check that it's compatible with the lake's bathymetric maps - a lot of budget models have limited or outdated ones, and that's where you lose the real usefulness. The Garmin and Lowrance you mention are reliable, but there's a detail that the others didn't bring up: check first whether the screen is big enough to read clearly in direct sunlight, because a lot of compact portables become unreadable at certain times of day. Then it depends on how you fish - if you're using a boat or fishing from the shore with a float rod, your needs change quite a bit.
Don't get hung up on brand names: at 200-300 euros you can find lesser-known brands that work just fine on Lake Como, like Deeper or some cheaper Humminbird models. The real thing is that a fish finder on the lake is mainly for understanding the bottom morphology and finding thermoclines, so the frequency matters more (usually dual, 83 kHz and 200 kHz) than the name on it. If you use it occasionally, check out the wireless models you connect to your smartphone: they cost less than half as much, take up the space of a lighter, and for Lake Como they're more than enough.
I've seen people spend less and regret it after three outings, so the budget you mention isn't bad if you really think you'll use it often. The difference between a 200-300 euro one and an 80-100 one shows up mainly in screen clarity in sunlight and signal stability when you switch zones - on Lake Como where depths vary a lot, that matters.
What bugs me though is that you never mention which fish you're after or how you fish. With a float rod from the shore a portable fishfinder is almost pointless, but with trolling or from a boat it's a whole different story. If you're on the bank and just want to figure out where the deeper zones are, even a basic one works fine; if you're on the water and need to track movement throughout the day, then yeah, Garmin and Lowrance hold up. The other big thing is that a lot of budget models don't read Lake Como's bathymetric maps well - double-check that before you buy, because that's the difference between a useful tool and a souvenir.
I had the same doubt a while back and eventually went with a mid-range model, but here's the real point: on Como the depth varies quite a bit, and a decent fish finder actually makes the difference between "I see something" and "I can actually read what's down there". It's not so much about spending 300 euros versus 100, it's that below 150-200 you start losing accuracy in the readings and the battery doesn't last as long. It also depends on how you use it - if you're constantly taking it off and putting it back on, a sturdy model with good battery life is an investment worth making.
What nobody's mentioned so far is the display trade-off: a lot of compact models in that price range have small screens that are only readable at certain angles. On the lake, you're always moving around, sun glare bouncing off the water... a mediocre screen will drive you mad. Personally I'd rather spend a bit more to get something I can read well in bright conditions, rather than one that "technically" works but I have to sit in the shade to make sense of it. And bathymetric maps are essential like they said, but check them before you buy - not all budget models have them pre-loaded for Como specifically.
