It offers audible alarms for critical safety alerts, user-replaceable battery, and compatibility with PC dive log software. Compact and durable, it’s designed for easy use over drysuits and rental use, making it the perfect entry-level dive computer for millennial divers seeking reliability and simplicity. ## Description Leonardo is the first dive computer designed and built entirely by Cressi. An elegant expression of simple, functional design, the Leonardo is a must-have for divers entering the sport and those who “just want to dive.”A single button interface makes it effortless to program Air, Nitrox and Gauge modes the first time a diver picks the computer up, and an edge-to-edge, high-definition screen gives large numerical displays in a computer that is still compact and travel-friendly. The clearly visible battery life indicator and distinct audible alarms deliver critical information as well as peace-of-mind during the dive. The Leonardo can also be fully re-set after each use, making it an excellent choice for rental departments. Review: The computer itself is brilliant. Out the box it feels really well made - Recently qualified as a scuba diver and decided to opt for the Leonardo after much research and fellow reviewers comments. I'm thankful I did! The computer itself is brilliant. Out the box it feels really well made, has a nice big strap for going over the drysuit and a large screen to display information with a protective casing over the screen itself for durability. The strap looks like it can also be removed and the puck integrated into your regulators which is a nice bonus. After trialling it at the weekend for the first time, it didn't disappoint in terms of functionality and ease of use. Before jumping in the water it allows you to plan your dive via the Plan screen which lets you set your intended depth and gives you information on required decompression stops depending on input. Air settings can be changed to allow support for various nitrox blends up to 51% in 1% increments which is also pretty handy. In the water, the screen automatically changes and provides information on your dive such as duration, max depth, current depth, next decompression stop and ascent speed with audible prompts for the more critical safety factors. I've not linked any of my dives as yet via the PC Link as I am yet to purchase the docking station (my only gripe!) so can't comment. Will update the review when the time comes! Edit: Purchased the PC Link and uploaded a total of 15 dives. The PC application interface could do with being updated, looks like something from the mid 00's. Information provided is great however, including tissue saturation. Since upgraded to a Suunto Eon Core as the screen wasn't great for those dark loch/night dives, but still have this as the trusty back up! Review: ちゃんとしたメーカーの物です *2020年追記 - ダイビングコンピュータが欲しいけど高くて手を出せずにいましたが、この商品は他よりもやや安いので意を決して購入。 やはりダイコンがあるとダイビングの楽しさが広がりますね。 ただガイドについていくので無く、自分で水深や時間を確認できるのは快適です。 ボタン一つでログも見直せます。 あと電池交換が自分で出来るのでランニングコストにも優れています。 *追記 ソーラー電池式に興味が出てほかに(aqualung calm)買い替えたのでレビュー追記。 初めてのダイコン購入としておすすめできるのは変わりませんが、8万円クラスの物と比較するとログ付けがすこし面倒だったんだなと分かりました。やはりボタンが一つなのは操作性としてはイマイチでした。 でも水中では大画面で見やすいし、初心者には嬉しい機能の浮上スピード表示がこれにはあります。 中性浮力を取る、セーフティストップを安定させる時にこれがあると便利だし、技術の向上には最適です。 ベルトが長すぎる！という人がいますが、不要な部分は切りましょう。 大画面のダイコンは腕以外に付ける人もいるのでベルトは長く設計されているのでミスではないんです。 買ってすぐに切るのは怖いでしょうが、腕以外に付ける予定のない人は迷わず切ってください。 ネガティブなことも書きましたが、ダイビング始めて一本目のダイコンとしては最適だと思います。 3万円出せばSUUNTOとかも選択肢ですが、正直値段ほどの違いはありません、ボタンが増えるくらいかな。 とにかく良いやつが欲しいというなら7万円以上するソーラー式一択ですが、初めてのダイコンなら絶対これでいい。 もしその後買い替えてもサブで使ったり他の人に貸したり、持ってても損にはならないです。おすすめ。 ## Features - Colour: BLACK / GREY ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0058UTZFI | | Age Range Description | Adult | | Band Color | Black | | Band Material Type | Plastic | | Brand Name | CRESSI | | Case Material Type | Plastic | | Clasp Type | Buckle | | Colour | grey | | Compatible Devices | PC, Laptop | | Compatible Phone Models | Compatible with iOS and Android devices | | Connectivity Technology | Infrared | | Controller Type | Push button | | Customer Reviews | 4.3 out of 5 stars 545 Reviews | | Display Type | LCD | | GPS | No GPS | | GPS Geotagging Functionality | No GPS | | Global Trade Identification Number | 08022983048215 | | Human Interface Input | Buttons | | Item Dimensions | 10.2 x 10.2 x 10.2 Centimeters | | Item Weight Unit of Measure | 200 Grams | | Model Name | Scuba Diving | | Model Number | KS770050 | | Product Features | Scuba Diving Modes, High-Definition Screen, Audible Alarms, Water Resistance (IP68) | | Resolution | 44 millimeters | | Screen Size | 44 Millimetres | | Screen Size Unit of Measure | 44 Millimetres | | Shape | Round | | Special Feature | Scuba Diving Modes, High-Definition Screen, Audible Alarms, Water Resistance (IP68) | | Sport Type | Diving | | Style Name | Modern | | Supported Application | Alarm | | Supported Satellite Navigation System | GPS | | Target Audience | Unisex Adult | | UPC | 843607035651 785571973822 | | Water Resistance Depth | 1 Metres | | Water Resistance Level | Water Resistant | | Waterproof Rating | IP68 | | Wearable Computer Type | Smart Watch | | Wireless Communication Standard | Infrared | | Wireless Compability | Infrared | | Wireless Provider | du | ## Product Details - **Connectivity Technology:** Infrared - **GPS:** No GPS - **Shape:** Round - **Special Feature:** Scuba Diving Modes, High-Definition Screen, Audible Alarms, Water Resistance (IP68) - **Wireless Communication Standard:** Infrared ## Images ![Leonardo - Scuba Diving Computer - Air | Nitrox Modes - Colour: GREY/BLACK - Image 1](https://m.media-amazon.com/images/I/71TJwEY-XCL.jpg) ## Questions & Answers **Q: Is it come with transmitter ?** A: This computer does not have a transmitter. Leonardo computers are not air integrated.Thank you **Q: Does this give a readout for the actual depth during a dive? Also, I assume it has a clock function, correct?** A: It has the actual depth as you dive and deepest depth reached during the dive. It has a clock function with either 12hr or military time. **Q: hi, 1. Does it support the metric system? 2. How can I replace battery?** A: Hi Alon, As a dive computer it can be set for metric or imperial. The batteries are user changeable as well. If you have any other questions just let us know. Thanks, Bill PADI Master Instructor **Q: Does it automatically detect when you are diving or you need to activate it before diving?** A: Hello, before diving must turn on the computer, when immersed the sensor at a certain depth is activated and goes into dive mode.Greetings and ThanksDavid ## Customer Reviews ### ⭐⭐⭐⭐⭐ The computer itself is brilliant.
