I bought this to replace a Montana 700 on the deck of my sea-kayak. The USB socket was dying, and it’s too heavy really for where i was using it. No physical buttons, just a touch screen, weren't really workable on the sea all the time either. Before the Montana the GPSMAP 66 was what I used at sea. This was the best unit at the time and worked really well. Small screen, light weight, physical buttons, AA batteries that lasted over 3 days. All good really. Soon to go to eBay! The H1 has big shoes to fill. It does look very capable. The buttons work in a similar way to the 66, so it’s very familiar. The larger screen helps for mapping. But no corner fields as I’d got used to on the Montana. With the touch screen off it’s easy to control and for me the interface needs very little tweaking. Mapping and compass are easy to get to out of the box as it is. Switching the Compass to CDI and turning routing off makes it work on the sea exactly the same as the 66 and the Montana 👍🏻. I can’t see all that much of the map when I have 4 data fields on display. But I can live with that. The Action button on the side cant be configured to toggle the touch screen, with is a big -ve. Activity tracks and courses seem to be readily accessible nicely. But saved activities building up over a few days cant be moved into a collection on the device by the H1. I have to do this in Garmin Explorer, which isn’t Garmin’s best ever software tool. I try and stay away from that as much as possible!! Having different profiles available is good too. I have only 3 : Kayaking, Walking and Driving. Though I wont use it much while walking. I prefer the simplicity of my Fenix for following courses and recording walks. The talky Toaster Map is very good too., much better than the Garmin Topo mapping. Though for real detail I use either a paper map or a selection of mapping on the phone. The InReach capability I look forward to playing with. I recently bought an InReach Mini 3 Plus which I used on my last paddling trip. This ‘just worked’ sending comms over satellite when we had no mobile signal in the Far Northwest of Scotland. The subscription is now suspended so it really just a replacement for my soon to be eBayed PLB. I wondered if I should get inReach on my next GPS. I decided if I did I could simplify further my kit list. I can easily use the SOS button if I want to while on the sea, so all very +ve I think. One ‘quirk’ is the spine mount. It can be threaded top and bottom with 12.7mm thin webbing tape, if you can find any! It’s an imperial size, not really sold anywhere I can find. Garmin won’t sell me a few m or more of their tiny tape loop things without a carabiner, a bit -ve in my mind. I can work around it by threading the slots with Dyneema Paracord so I can fix it to my spray deck well enough I think and detach it at the end of the day to charge, etc. Overall I am quite pleased with the GPSMAP Hi1 Plus. It will do a great job for what I want. I look forward to seeing exactly how long the battery lasts over a few days use 🙂. PS … it did get stuck in the endless reboot cycle once 😮. A quick search of youTube revealed a fix involving a long press of the power button to switch it off, then hold down the page and enter buttons at the same time while pressing the power button once. It churned away and fixed itself 👍🏻.
